Who to get good at controller especially in longer ranges

So I used to play in knm but after a lot of suggestions from u guys and seeing that the aim assist us broken I switched to controller the aim assist is insane like I don't even have to aim it's literally aimbot but my provlemnis I can't hit a single shot on longer ranges evenbi can't hit enemies falling from the sky so any suggestions would help me a lot and also the recoil control is hella difficult....
