I have actually met a few professional athletes. Many people are born without the qualities (height, build) to professionally play anything, that's true. However, those qualities confer a relatively small edge in most sports compared to the things you can train: strength and skill. The reason most professionals are physical freaks is because nobody but those people can get that edge, and professional sports is about finding every edge you can get.
