Came here to say this. All varmints are critters, but not all critters are varmints.
Also, sometimes a creature can be an occasional varmint, a sort of shrodingers varmint. Is a raccoon a varmint? It both is and is not until you find out if it’s dinner, a pet, or eating your maters

Also, as you noted, it’s varmint, not varmit. It’s etymology is vermin. Sounds like something a yank would get wrong (as a half-yank, I can speak to this).
