We should not because if we do we are prone to losing a lot of money there is no use getting affected because luck in gambling is not just a result of effort it is more of luck and we don't know who and when will luck strike next.
I'm a lotto bettor and I have seen huge jackpots won by construction workers I only feel good to the guys for hitting the jackpot and getting a chance to change their lives for the better, there is no use changing how we gamble as long as our routine is safe.
Indeed, gambling is a game of chance, there is no guarantee that you will be able to get a big win or jackpot. With those who have already won a big win or jackpot, it is indeed because of strong luck, but that does not mean that all gamblers will definitely get it, of course only a few gamblers can get a big win, because gambling is based on luck and right what you said, we don't know who and when luck will come, because of course luck is only occasional data but in gambling many gamblers waste the luck that has been obtained because they follow their greed.
It's true, there is no point in changing the way we gamble, the point is not to be obsessed with winning at gambling because we must be able to see, the chances of losing are greater than winning that cannot be changed. It has become a permanent fixture, therefore gamblers will generally only experience loss or defeat in the long run.
