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.
I wouldn't say that it is easy to hack/cheat in online gambling, but current security measures are implemented on the popular websites in my opinion and knowing that it would just be stupid to cheat because it's not the right way. You should be thinking about how you could improve your chances, not participating in illegal things that could lead to easy money, but that's just stupid.
