I think there are several aspects to this. First good athletes often have very good body awareness, but also and this is quite important as well, they are used to working and practicing with only seeing small immediate gains. In my experience many people who take up dancing see very experienced dancers and expect they will be able to do this after one or two courses. They then get frustrated, when they discover it's difficult and simply give up.
