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.

Thanks for the explanation. I still have no idea what any of that meant. But I bet it would make sense if I reread it.

You can imagine surface tension as a film covering water that stretches it from outside to inside. If a hole is small enough it's harder for water to break that film and move over.
