Luck is not something that you can acquire or do anything to influence its appearance, if you get it on your side then good for you as you may get some profits during that period of time, however as we know the odds are against us when we are gambling at any casino, so given enough time regardless of how lucky a person may believe themselves to be, eventually their luck will take a turn for the worse and they will give back any money they may have won during that lucky streak.
Does this mean that even with luck on one's side, the casinos will always win? Do you think there are no people who have made fortune from casinos? I don't think I agree with you because there are people who have won millions of dollars from casinos who may have invested the money properly, they will not give them back to the casinos even if they experience the worst of bad luck.
The casinos will not always win, if that was the case then no one will gamble as what it is the point of playing a game in which you know for a fact that you will always lose? However it is an unlikely occurrence and winning big is even more unlikely, and while you hear all the time about the lottery winners and the great fortune they made, something that is not often mentioned is that the majority of those people go bankrupt just a few years after their big win, as they had no previous experience with that amount of money and they do not know how to manage it.
