So, unfortunately, gambling is based on luck. i am not the best person to say this since i am not good at math, but i think it's important to understand that casinos don't randomly play losing games. They expect to make a profit, and so in my opinion, the payout percentage isn't exactly fair.
Well you cannot blame the casino completely at the same time because for them too they are out there to make profits and ofcourse the gamblers will have to loose a game for them to start counting their profits as a business. As a gambler it is important to understand this and make sure to protect yourself that you are not loosing to the point you have to start looking for whom to throw the blames at securing you feel you were deserving of a win and lost, knowing you are depending on luck ti an extent, you should put to consideration that you are going to manage your bankroll to the point whereby you do get chance with your bankroll been in the best position to make you money and not you loosing all to the casino at once.
