After enough large number of rounds the theoretical distribution of the total win converges to the normal distribution, giving a good possibility to forecast the possible win or loss. For example, after 100 rounds at $1 per round, the standard deviation of the win (equally of the loss) will be 2 ⋅ $ 1 ⋅ 100 ⋅ 18 / 38 ⋅ 20 / 38 ≈ $ 9. ...
