There is no business where you can get guaranteed success so luck will let you down for everything gambling is no exception. Because gambling requires you to take risks and put your mind to the fact that you will win. In my area very young children are also busy with online gambling but why is that? Because they are winning, the attraction to gambling increases. It is not unusual to gamble every week but you have to be quiet that the pocket cannot be emptied. If your income is high then you can easily control and play. But i have seen it is more harmful for the student body because they have no source of income so they indulge in other vices to earn gambling money.
Yes, they are continuing to gambling online because they are "winning" which can be consider as a bad thing since it can lead to gambling addiction. Gambling could be considered as investment for some people as their spare money could be doubled or tripled by winning, and of course they are aware of the risk of losing as well. These young people have tasted the sweet victory of gambling and would want more, the greed will follows as they keep gambling, they would suffer a big loss and they would never stop as they would try to recover their losses. I mean they can stop themselves into gambling as they are limited with funds since they don't have money sources like income or salary, but eventually they would try to comeback hoping to win or recover.
