The honest people are a larger group than the dishonest people.

And being real, the zero-day cheats are closely guarded and trickled out and sold for high prices as other cheats get found out, so for AAA games, the good cheats are priced out of comfort zone and anyone who attempts the lazy/cheap cheats is banned pretty quickly. A significant portion of the dishonest becomes honest through laziness or self-preservation. Only a select few are truly committed to dishonesty enough to put money and their accounts on the line.

Same way there are fewer murderers and thieves than there are non-murderers and non-thieves (at least in western countries).
