Are shorter guys naturally better wrestlers and weightlifters?

usually a good wrestler is short in combat sports like the UFC, and most power lifters are like 5'6-5'8 because they are powerful and don't have to move their limbs very far to push the weight. are guys around this size just more well suited to being a wrestler or a weightlifter? I am 5'11 myself and can beat up my friends who are like 6'2, but the ones around 5'7 or 5'9 are just so damn strong!
