reported by Politico that four people speaking regularly with VP Biden had privately told the mhe was unlikely to run for reelection in 2024

The Politico article quoted several anonymous people and in it they only shared their personal opinion and not anything that Biden said. So your description of that article is wrong, you are lying.

I’ll provide quotes:

“If Biden is elected,” a prominent adviser to the campaign said, “he’s going to be 82 years old in four years and he won’t be running for reelection.”

Anonymous personal opinion.

“This makes Biden a good transition figure,” the adviser said. “I’d love to have an election this year for the next generation of leaders, but if I have to wait four years [in order to] to get rid of Trump, I’m willing to do it.”

Anonymous personal opinion.

Another top Biden adviser put it this way: “He’s going into this thinking, ‘I want to find a running mate I can turn things over to after four years but if that’s not possible or doesn’t happen then I’ll run for reelection.’ But he’s not going to publicly make a one term pledge.”

Anonymous personal opinion.

But none of these are relevant, because shortly after the campaign responded:

"Lots of chatter out there on this so just want to be crystal clear: this is not a conversation our campaign is having and not something VP Biden is thinking about,” deputy campaign manager Kate Bedingfield tweeted.

Not anonymous and an official statement from the campaign.

So I repeat myself:

Anonymous people said that they thought he would, and when journalists immediately asked the Biden campaign they denied it. For some reason people take as gospel what anonymous people thought someone else would do.
