I believe the parent commenter's argument is that they instead play the game with multiple people. The increased chance is not per person, but achieved by using more people, each with their own chance.

I don't know if they do this, I merely find the argument itself intriguing with the shift in perspective, and that you as the reader has to keep track of the change in context from the individual one level up.
