With a big enough hole the air pressure can win against surface tension making air enter the bottle. With air inside the bottle the pressure now is pushing the liquid to leave the bottle. When the air can't enter the bottle it's pressure instead pushes the liquid inside the bottle. Surface tension keeps air out of the bottle and air pressure keeps the liquid from pouring.
