The consequence is the risk of addiction because of its easy access and because online gambling can be accessed anytime and anywhere, people can become addicted to playing continuously, which can lead to addiction and can be financially detrimental. And in the long run I think there is no online gambling that can make people successful, except winning the jackpot and then stopping.
Yes, this is the biggest risk for gambling as playing is now very accessible to everyone. We even don't know if kids are playing more often today as they can easily register on any gambling platform. There are even instances that they uses their parents credit card to play.
Online gambling or traditional gambling was created not to make money, but only for entertainment and can be a fun way to spend free time. And besides that it can improve your mood positively, create happiness and can also improve your skills or you can gain skills while playing. And it all depends on your goals when gambling, and if you aim to make money it will only make you play without control which will lead to addiction because you will be controlled by the game not the game that you control.
Regardless of what purpose it is, we should be able to control ourselves and not get addicted by it. You mentioned some positive effects of gambling, and it could really shake our mood into more positive specially if we win sometimes.
But it should not be treated like a regular job that you can make money and bring food in the table for your family.
