In one sense, winning bets. If you lose, you lose: your money is gone either way. If you win, the fact that the probabilities sum to about 1.05 means you win less than you would have in a fair game. The state just takes a cut of that extra 0.05.
If both outcomes have a probability of 0.999 (summing to almost 2), I'll barely make any money if I'm right, and lose my money if I'm wrong.
So when probabilities sum to less than 1, it's good for the gambler, and when they sum to more than 1 it's bad for them (and good for the bookkeeper).
