exactly that is correct as Houses always win and we must accept that , maybe at some chances we can beat the house but in regular playing? it will keep winning and may take everything that we previously taken to them, so best to gamble only the amount that we can manage to risk and lose so there is no tears shedding in the coming days.
Since the House always wins, we must minimize our losses so as not to lose too much money.
I doubt we can beat the House, even if we can beat it, the amount we win won't be as much as the House will get.
But people like that don't care about that and keep playing and taking risks and in the end, they lose gambling.
We must know ourselves by not taking bigger risks, especially if we are not ready to see it and better stop before it's too late.
