When I started gambling earlier, I believed in the power of amulets and so on, but time has shown that it is completely dishonest, at least for me. But I tried to believe that they would bring good luck, in general it looked very funny at that moment, I believed and begged to win the bet using the power of the amulet, but the bet lost. After several such events, I did not go looking for a new amulet, but simply realized that it was all nonsense, and luck itself decides who to choose as the winner.
As for the OP’s story, it’s really creepy, probably the man was right, because some people addicted to the game will be forced to do things that they would never do in their life and this sometimes causes fear in me.
That's normal to sees some people who are new in gambling use amulets to playing gambling because they hear some people that use the amulets can wins so they try to use the same things. They hopes they can wins when playing gambling so they still trying to use the amulets but the facts that will not helps them to wins. But you finally realizes that will not helps you to wins the games and not trying to use the amulets.
When someone doing something too often such as playing gambling too often, they will wants to wins the gambling games and will do many ways to wins, including using amulets to helps them wins. But they must not thinks that can helps them wins the games because luck will decides who deserves to gets luck and wins the games. If gamblers realizes about this, they will not use amulets and just enjoy the gambling games because they only wants to have fun to playing gambling.
Yes, bringing amulets while gambling is not prohibited, but will he try to be honest or open about it? In my opinion, NO, because if he is caught, he will feel embarrassed and will hear a lot of taunts at the casino. Because nowadays there are many gamblers who do not believe in mystical things, gamblers now rely on their intelligence and insight in every gamble so that they consider losing or winning to be the real result.
Maybe they will honest with themselves when playing gambling and carry the amulets but they hopes they can wins using the amulets. But they must trying to realizes that using amulets when they playing gambling will not increase their luck to wins because no one will knows when luck will comes. That will makes them not to depends with the amulets and only use some money to playing gambling so they will not difficult to stops their gambling activity.
Many gamblers nowadays doesn't believes in the superstitious things, especially gamblers who playing online gambling. They don't thinks that superstitious can helps them to wins because gambling is not a magic and they must have luck to wins the games. They must consider not to playing gambling too long and with too much money.
