"admitting" could also be in the sense of "disclosing". I wouldn't expect anyone, even an elected leader, to immediately disclose a health issue that requires some amount of understanding and decision-making.

There's a segment of the population that thinks he knew while he was running for president but didn't disclose or "admit" the issue to the public. Given that this is an aggressively metastatic cancer, and Biden's campaign ended nearly 10 months ago, I think that's implausible to the point of being ludicrous.
