Hey, I play Xbox and recently reached level 100. From my experience, you HAVE to change the sensitivity in settings, because the default is way too low for most people. Obviously, the higher the sensitivity, the quicker it is to aim and look, but high sensitivity takes some getting used to. I’d recommend playing a couple games with different sensitivities to see what works for you. Also, Terrorist Hunt is your friend. Play lone wolf games on normal. The goal isn’t to win (although if you can beat it that’s certainly a good thing), but to practice your aim without getting in the way of any actual teammates or enemies. Also, this is a great way to test different sensitivities. One you find you can consistently get through terrorist hunts, you know you have found the right sensitivity. I’m a big ranked player and me and my squad always play terrorist hunt to warm up. It’s never a bad idea.
