Do whatever will bring you joy! In a year from now you will have a big improvement so start now. If you have this idea it means your soul wants it, the universe will always support you on your souls desire, just make the first step!
At the beginning just start playing some games with basketball ball and basket. For instance 33 points. Just Google it. And then step by step improve your ability to play full game.
Well if your physical strength is present? Sure, any game can be played by a person till they are physical healthy and if you are tall? Even better!!
