"If my chess team of 45-year-olds were 10 years younger, I would win more games." Is this also an ageist logical inconsistency? At some point claims like this are testable. On a separate note, of course 20-year-olds are better at their jobs than 100-year-olds. So the phenomenon of younger people being better at their jobs is true at an extreme. You can argue that it doesn't extend much further than this extreme, but saying it doesn't exist at all is silly.
