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.
winning is always the main factor for an addicted gambler because feeling an excessive sensation of pleasure will increase the dopamine hormone in our brain and everything turns very bad when the gambler cannot control himself or control his emotions of pleasure which will always provide a high risk if it can be done in the long term.
honestly, I don't really like someone who considers gambling part of an investment because this is something that carries the risk of losing money, and someone can even lose large amounts of money in just a few minutes. maybe rich people can consider this as an investment, but if you really want to invest, it's better to use your money in other investments that have a lower risk because gambling is not for profit and is just for fun without expecting a big win and if you win big, we can get it is just part of the bonuses given to us.
and regarding gamblers who chase losses, this is just a wrong mindset because they dont understand that chasing losses is the same as losing large amounts of money because as I said before, gambling is just a slightly luxurious entertainment and we won't win as long as we're not lucky.
