I am not sure if there's any public data regarding that. But it has been estimated that the illegal market of cheats is worth about 100 million. Many cheaters don't even intend on playing against legitimate players, looking for so called "hack vs hack" games. At some point CS2 didn't really act on cheaters for a while and it got really ugly. Anti-Cheats do work, there will always be ways around it but as long as these alternative paths are inconvenient enough to prevent a consumer from buying the cheat then it works. Without Anti-Cheat modern competitive games are unplayable.
