That is listed as number 241 on Wikipedia. I will look and see if I can find the discrepancy.
Update:
Wikipedia, it turns out, is not missing any EVAs, they just have the label for 100th in the wrong place (one EVA later than it should be). It's based on a NASA status report that claimed the February 14, 2001, EVA as the 100th but it appears they issued that statement one EVA too late by mistake. I wonder why that happened at the time, though.

Good of you to catch that error.
So that still leaves the question of how NASA came up with the "300" number in their July 13 press release.
Maybe this is how: if you include the seven LM equipment jettisons on the lunar surface, then you get 300 US EVAs (293+7). Could that be it?

I asked NASA public affairs to clarify and if possible, provide a list of the 300 spacewalks. They didn't have a list to share, but confirmed the above:
...some of the technical definition of spacewalks involve the opening of a hatch during Apollo and tossing trash out.

That begs the question, why did they decide to count those now and not in the past? That would mean rewriting the books and changing when the 100th one was too.

I inquired to NASA and got the following list back:
169 EVAs out of ISS airlocks
82 EVAs out of Shuttle airlocks
3 outside the Mir Space Station
10 outside Skylab
21 at the moon (including stand up EVAs to discard trash)
4 outside Apollo command modules (for photography or film retrieval)
9 outside Gemini capsules
By my count, the number post-Skylab is 253 but NASA is saying 254 here.
(They show six for lunar trash).

By my count, the NASA list has one too many ISS spacewalks (it should be 168 before today) and one too few Apollo trash jettisons (it should be seven).
So the total is still correct, but the breakdown by program accounting is wrong.

To prepare for two of its astronauts marking a new milestone in space, NASA has decided to rewrite the records for many of its historic missions, including the first moon landing.
As history records, Apollo 11 crew members Neil Armstrong and Buzz Aldrin performed the first-ever moonwalk on July 20, 1969, 51 years ago Monday. The astronauts' 2-hour, 31-minute and 40-second outing to explore the lunar surface was recorded by newspapers, historians, authors and by NASA, itself, as the mission's only extravehicular activity, or EVA, the technical term for spacewalks.
But with a recent press release, NASA effectively added a second EVA to the first moonwalkers' credit — and the agency did not stop there.

Whenever EVA numbers come up always brings up the question/rumor of an EVA on STS-27. Did it happen or did it not?

This was not counted above as an EVA, but it is worth noting that the Skylab 2 crew was suited up in a vacuum in the command module to troubleshoot their docking problem. The side hatch was not opened, but the overhead hatch was opened and the docking probe was removed and inspected. Conrad called it their second EVA, and it was referred to as an EVA in a Skylab press conference.

Cassidy and Behnken the first astronauts to conduct all 10 spacewalks in a NASA EMU suit.

In this NASA video from Sept. 8, 2020, there are all four EMU units around Chris Cassidy, but the left one has the Russian flag on its left arm. Is it any schedule of US with Russian spacewalk or 20th anniversary of the ISS only?

I believe the EMU is configured for Anatoli Ivanishin just in case an emergency EVA is needed while the space station is still limited to only three crew members.

It looks like that flag is upside down on the suit arm.

The first Russian space walk from the Poisk module is scheduled for November 2020. Orlan-MKS suits are already in the Poisk module.

Where will Kate Rubins be during that spacewalk?
Soyuz MS-17 will be docked to Rassvet, so I'm guessing that she will not have to stay there during the EVA. Is that correct?

If all goes well I think it will be exactly what you guess. Certainly, more details will be known closer to the space walk.

That EVA is currently planned for November 18. It will be the first Russian EVA at the ISS since May 29, 2019.

Currently onboard the ISS are five EMU units: 3004, 3006, 3008, 3009 and 3015 after CRS-21 Cargo Dragon delivering the last one. EMU unit 3008 will be return to the Earth on that craft in January 2021.

From Guinness World Records (via Twitter):
With 15 years and 214 days between spacewalks at the International Space Station, congratulations to JAXA astronaut Soichi Noguchi who's set a new record.
