As someone who also has thousands of hours in counter strike, you are either playing up the number of cheaters in the game (many do this, because they don't like to admit when someone is simply better), or have been extremely unlucky. I'm assuming here that you are talking about prime matchmaking, I don't have much experience with non-prime.

Valorant anti-cheat is a throwback to early 2000s malware, not really years ahead.
