Everyone wants to be better...I guess some people don't, but that seems terribly boring so lets pretend that doesn't happen.
Everyone wants to be better.
Less people have the fortitude to push themselves to be better.
Less people have the knowledge to take full advantage of that fortitude.
Less people have the patience to hone their knowledge and fortitude into actual results.
Sure, some people are born with more advantageous biomechanics or muscle fiber composition, but there are plenty of people with mutant physiology who grossly underperform because they can't get their heads on straight.
