Well, that's not always the case. Sometimes even if you have techniques or whatever that we do to make losing slow down, if not prevented it's not enough, remember, when we are betting, we depend on luck and not just any beliefs to win.
There is no such thing as believing that you will win. If everyone keep losing and no one wins then how is it possible that people keep coming back to the site? There is a thin line between a smart and a lousy gambler, for me I dont keep on rampaging my money when I lose in fact I tend to find and gamble EV + bet
It is like there is 10 player, a casino gives 1 player to win and actually the funds is taken from the rest of 9 player.
Because there is house edge , then they take percentage from there , that's why it called 'everyone lost'.
