This is evident just looking at basketball... the fourth- and fifth- year players on a team like Oakland manhandled the more talented, but significantly younger, players at Kentucky. Sure, the talent difference was remarkable... but when the game gets more phyiscal, that difference can be mitigated.
A lot of people like to compare the top college teams with bottom NFL teams... "Alabama could beat ..." this year it's U Conn could beat some NBA teams. No. No they could not... 18-22 year olds could not beat teams that are just as talented but 8 to 10 years older, stronger, and more experienced.
Consider how many rookies go from college to starting their first game and succeed. For every CJ Stroud there's plenty of Ryan Leafs... and there is even more disparity for the late rounders.
