I won't agree that the more you roll the more you will lose, sometimes you will win. As I have said dice game depends on your luck, there is a chance that you can defeat the house edge if the luck is on with you.
You are missing the point. Have you ever heard of anyone winning regularly from gambling in the long term? Probably not. On the other hand, you would have heard tons of stories about people winning big with a single roll thanks to insane luck.
This is why short term profits can be expected and this is why many people like to go all in on their rolls. Sports betting is far better for earning regularly in the long term since luck is not the only factor involved here.
