I agree with what you said, it's better that you play gambling for fun than you play gambling to make money. It is difficult to make gambling a source of income because we know that there is no certainty in gambling whether you will win or lose. The first thing that will happen to you is that your money will run out, you will become addicted to gambling etc. You will not get rich immediately from gambling always remember that so don't be serious about gambling, just play according to your budget and have fun. It's really tempting when you often win gambling, but you have to control yourself because it's not always like that, it's rare to win big in gambling.
Gambling for fun has always been better as against gambling for the purpose of making money because in the end you don't make good profit if you are not lucky enough, you mostly only break even if you are lucky or in most cases you even end up loosing more money because gambling has never been a sure way of making money as it's always been a 50/50 chances of winning so it's always much better you put your mind to making it just fun rather than hoping to make money from it so you don't get to suffer from losses when they occur.
The problem lays with most gamblers as they don't want to gamble just for fun, they mostly want to make money gambling and that's something that's almost not really possible except with lucky few who happens to make some good money gambling.
