gambling is more on losing that success so at least you have already learn that now
No for me, there are just some people who are very lucky, like the universe is with them and there are people who are unlucky. I know being lucky is also siginificant in gambling. If there are more losing on gambling then it should not be popular, I know some people who are make living by just gambling.
Fortunately, gamble is about luck that provide success and if it runs on our individual way then we can be fail. As a gambler, we must accept sportsmanship and its consequences. We must take gamble as an entertainment that give profits even in a modest way.
A good approach to keep the environment cool but you might know of its risks where you cannot stay calm all the time. When you lose more you will get hurt the most that is why you cannot take it as an absolute entertainment source. However, the efforts are not bad because there is no point if you want to make money while spending the time in risk and pressure does not make any sense.
