Earlier quoted context omitted.
Context helps. A lot of really strong players are 12 years old.
That context doesn't help me at all. Is a "really strong" 12yo in contention to win this particular competition that a 35yo won?
In chess there’s a concept of strength, and ELO is used as a rough estimate of this. Further there are FIDE rankings like IM and GM that have certain requirements to achieve.
In most sports, there’s never such an age gap. Think of basketball or football. You don’t see 12 year olds hitting the equivalent of GM in those respective sports (going pro?) and being able to compete with the 35 year olds, do you? In most sports, they wouldn’t even be allowed to enter but in chess they could.
