Not all wagers are on games of pure chance, such as slot machines or rulette tables.
So what? What does that have to do with anything. I am not redefining "games of chance" by saying "wagers or bets." I am instead listing different types of things we know as "gambling."
Would we agree that gambling involves some type of risk for a greater reward, based in part or whole upon events that are out of our control?
