I think is important to note that casinos are businesses, and like any business, their ultimate goal is to make a profit. While casinos may offer promotions or bonuses that increase their customers' chances of winning, these are ultimately designed to attract more players, which in turn will lead to higher profits for the casino over time. That being said, it is still possible for individuals to win big at casinos, but it is important to remember that this is largely a matter of chance, and that the house always has the edge over players in the long run.
