I think for ordinary players it is difficult to get win after win at the casino or make money from gambling because of the limitations they have so it will be very different from the whales. But it's a different story if ordinary players can get luck that will come suddenly so that it can help them get big wins. Therefore, it is better for ordinary players not to depend too much on gambling and expect too much to make money from gambling because it will be difficult. Maybe they just need to play gambling for fun because maybe luck will come to those who don't have a goal to make money from gambling.
Gambling for fun is the right attitude to have as gambling for money is surely to end bad for the majority of gamblers that try it, however even then luck may not be on your side, the truth is that there is not really a reason behind why some people are lucky and some are not, some people try to explain this with superstitious beliefs but there is not any explanation for that, someone eventually was supposed to get lucky and it could happen to a person gambling for fun or for money.
Luck, if permitted, is for anyone who's gambling. Whatever the reason you may have once luck is triggered, you will win and there's no explanation for it. Even any superstitious belief can't give any reason how luck being done. One thing is for sure, once luck stands your back and lets you win a huge amount of money, it will be on your end to make a good call to enjoy that huge amount of winning money.
It's an opportunity that being provided to you, make a good use of it. Imagine it came from an almost dust money and because of luck, you make a million dollars out of it.
