Here's an experiment:

Person A: A 6 ft man

Person B: A 5 ft man

In basketball, even if person B trains for 23 hours/day more than person A, he is impeded because of his height.

Is there a guarantee that person A will do better JUST because of his height? No

Is there a guarantee that person B will do better JUST because of more hours invested in training? No

But person A can train and become better whereas person B cannot change anything.

Such is the nature of physical differences.

Person B would be better served playing a sport that doesn't require height...aka, Basketball is not "Optimal" for person B.
