@IrisHaze She could have, yeah. But he does have a point: Sure, being young is
associated with certain characteristics of, like, emotional immaturity etc., but like some old people are totally immature and some young people are less so than you might think, and may have other personal qualities that outweigh that. Rather than looking at a number and just going with the preconceptions associated with that, it would be more reasonable to look at the actual specific person. Maybe it turns out they do have kid characteristics that make them just not dating material, but it's fair to look at the individual.
