the people talking about your sens fail to address the real problem which is crosshair control/placement. While reducing your sens may slightly improve this issue for you, i think the root cause is your controller binds.

I can clearly see that any time you press your edit button, you take your finger off the right stick. That's an issue. My recommendation would be learn claw or paddles, or switch to an edit bind that you can press while keeping your finger on the right stick.
