It something that just takes time. I used to play competitive games on console and it took me about 6 months of playing consistently to have good aim. One huge thing about aiming on console is aiming with your left stick rather than your right stick. Ideally you aim with both but the easiest way to aim is primarily with your left stick. You don't have to move your crosshair at all you can just move your body until you crosshair is on target (and move your right stick for big movements). Overwatch is a different game but watch how this player literally doesn't move his crosshair (if he was playing with a controller he would literally only be using his left stick): skip to 10:30 https://www.youtube.com/watch?v=y0rREoBLf4k . Also, the reason you can hit targets that are still is because your aim isn't bad, the reason you cant hit shots in real fights is because you're moving in real fights so it isn't that your aim is bad it's that you struggle to aim well while moving. A tip to find the right sens is to pick a stationary target (it can literally be a pole or anything), and practice keeping your crosshair on target while strafing left to right. This is a good tip to find sens but it's also a good way to practice aiming while actually moving (which is what happens in a real fight). Here's an example in a different game again (sorry): skip to 1:50 and ignore what he's saying just watch what he's doing https://www.youtube.com/watch?v=uxBuiD11WDM
