We do teach athletics, but not as classes in schools. If you want your kid to learn how to play baseball, you sign them up for little league. Similarly for other sports. Coaches teach them how to play the sport.
Competitive clubs kick out (directly or indirectly) kids who don't do well instead of really attempting to teach them.
Especially in teams sports, if you want the kid to learn soccer/basketball/whatever and the kid is not a talent meant to win competition, coaches wont spend much time teaching the kid. You may pay private lessons or something.
