I am not good at basketball.
There has been research that states that one reason why people aren't good at sport is because of their mentality. For instance, if you think you are going to miss the shot then you will, but if you think that you will make the shot then you will. 
There have been plenty of easy shots that I've missed, Sounds like a bunch of huey.
There is an old saying, Don't knock it till you try it. Try it first and see if it helps improve your basketball skills. Sports are never easy and others make them look easy. Try not to think about how good they are but about how good you can be.
I don't play basketball anymore. I was so bad that I quit so I didn't embarrass myself.
Have you tried virtual basketball? CrazyGames has virtual basketball games that are fun and you can improve your players shooting, dribbling, and dunking skills. 
I don't like VR. It makes me nauseous.
There are some ways that you can not be nauseous while in VR. Have you tried standing up while you are playing? Or have a fan by you while you play. A fan blowing on your face has proven to reduce VR nausea. 
Sounds like too much work. I'll stick to regular old video games.
Video games can be really fun. The PS2 was actually made similarly to the Microbox which was created by Atari Falcon.
