Gambling and pofit in the same sentence is something you dont here everyday but certain games allow you to make some money like poker, but when its you against the house that should be for fun because it never ends well as the house always wins.
Where did you get the information that the house always win? If that is the case, there shouldn't be a single player playing dice or roulette or the like because they will just end up losing every time they play it.
where? it is everywhere actually lol , seriously you did not know about that fact?
house edge are a built-in advantage for the provider / casino owner. they will always get profit from the money that people gambled in their place. no wonder mathematically it is a sure loss for you when you do it continuously , just give it a try and come back here to prove what i have said. gambling won't be profitable.
