That's just clearly not true. Look at the high end of any sport and you see obvious genetic advantages. Basketball is particularly obvious, because height is so important. Nate Robinson could jump just as high at LeBron James, but at 1.75m (5'9") he was never going to be as successful at basketball as the 2.06m (6'9") LeBron. There are plenty of basketball players who would have never got on the court if they weren't as tall as they are. No amount of passion is going to make you taller.
