Gambling is the very dangerous game you can ever play in your life. Yeah, it's fun in the beginning because you're winning but don't you think that it's just a way that the gambling sites planned for you to get addicted to it to risk all your money just for it? Of course that thing didn't come in your mind in the first place because the only thing that you're thinking when you're gambling is you're gonna win no matter what and take back all the money that you've lost on it. The worst thing that can happen is like what happened to you and I'm very sorry to hear that too. I hope you've learned your lesson here and start living your life in a different way but better. Get a new start, it's not too late.
actually you will not always win at start,
there is no fact that the gambling sites make you win to lure you to play more in them,
gambling games are mostly based on luck
so we can't say that the house do actually control the result of the game,
Especially if you think of a games like poker,
then I supposed that you can't find a way to say that the house is controlling the result of it
since poker uses skills of the gambler and also their
analytical knowledge to control the result of the game.
