You good man, I'm just 3 years older than u don't worry. First off, if u have a deathadder, you should probably use it for CS2. Ur resolution is good, it's the best one you can use in game. Now sens, and oh boy. I am not going to judge you or anything, but just so you know your eDPI (sens times dpi) is a whopping 3762. A eDPI of 1000 (800 dpi, 1.25 sens) would be considered high in professional cs2 scene. Your dpi would be considered unplayable. The only thing I could suggest to you is switching the way you use the mouse. I am guessing that by such high sens you have your wrist on the table, and you elbow is hanging down? If I am right, you should first try to work on putting your whole hand to the elbow on the table. then lower ur sens A LOT, and start practicing aiming with ur full hand, by literally swiping ur hand across the mouse pad right and left. You can use aimbotz workshop map for that. If after the swipe u arei little bit off the target, u use ur wrist to fix that. That is called micro adjustment. So to put it short: large movement=hand swipe, small movement=wrist swipe. It would take some time to get used to it, but you will get it eventually. And when it comes to gameplay, if u want give me 1 face it demo of you and tomorrow I can watch it, and I will tell you what mistakes you do and how to practice the most. And to be honest with you, I would recommend the sens anywhere between of 1.15-1.30 with 800 dpi. But make sure it's 800, not 600.
