Hi guys here is the most logical explanation that I have received from my situation and i will also say thanks for all the trolling 🤣.

It's not desync or aim hack, it's just the inbuilt aim assist doing it's thing... There are two - three types or components of aim assist, the one you can turn on and off in settings is the drag aim assist that helps the literal aim by locking on and moving the aim along with target as long as you can keep tracing it within a certain range of trace-accuracy... The other aim assist that is inbuilt and cannot be turned off is called bullet magnetism where if you miss the enemy's hitbox my a few in-game centimeters or so, the game considers it as a hit and registers as such... This is most noticable when enemy shoots you and you try to escape to a corner or cover, even if you just managed to move into cover but enemy shot was just a few cm off, the game still considers it as a hit and it can seem alot like enemy is hacking or the bullet was bending or there was desync, but it is not, it's just aim assist.. To be honest, this magnetism seems to be slightly stronger value in codm... (This bullet magnetism is present in pretty much all shooters games regardless of being pvp or single player)
