What trick? Like cheating the gambling itself? If that is what you will do then it's possible but if you are talking strategies on about timing or patterns then you are just making it hard and more complicated for yourself. It does not help and it's just another creative way to lose your money.
People actually think or try to find out the gambling tricks forgetting that if this could happen people would have made so much money that casinos would have to shut down and not remain open if they start giving the money in this way.
People want an easy money and don't want to work hard will believe on these tricks and they don't want to accept these results are based on only luck. What you said is 100% correct. If any tricks work then many casinos need to close. That's why I usually fix small amount every month to play these games and try my luck. But so far got some luck in sports betting but in casinos games or dice no luck.
That is how it should be. Try your luck with a a certain amount each time and stop there. Thinking anything else or that you can change the games outcome is foolish and gamblers fallacy. I don't think k there will ever be tricks because it is all worked out before hand with maths.
