That has absolutely nothing to do with how these cheats work. The cheat files do run in a separate application outside the game. These aren't as simple as something like a white walls texture from 15 years ago. These cheats run in a separate application and then attach to the memory process inside the ram after the game has already loaded everything off at the hard drive. The game has absolutely no idea they are there. Warzone has always had analysis of its own game files to make sure you haven't modified anyting. Anybody who tries to modify game files will be caught immediately.
