It all depends on each person's perspective and point of view on gambling from the beginning he was involved, there are many factors that trigger interest at the beginning, starting from being interested because gambling is fun to do in your spare time or interested because there is a chance to win, so whatever developments will occur to a gambler that leads to their approach to gambling depends on how their perspective is from the beginning.
Yup, it's on you when you step your foot into gambling, how you percept the possibilities and how you treat your participation, the development depends from how you control your emotions, there are some who start as entertainment then ends up getting to deep and become addicted, whatever the age and the level of understanding once you exceed from your set target then you are already prone getting addicted.
Everyone have their reasons why they are gambling most are gambling because of the money or should profit they think they can make from it , and some are gambling for fun ( especially those that financially stable), but those that are doing it for money they can get from gambling are more common than those doing it for fun , most folks are addicted to gambling because of the way or the mentality they use to approach it , some gain such mentality from things they came across, like those showcasing their winnings via social medias just to get more engagement not knowing they are endangering Young folks lives , because they have given them the mindset of believing gambling is the easiest and fastest way to eradicate poverty, which it's isn't because it can also lead to that same poverty if is not being approached wisely.
Now the trend among young people is gambling and betting, because their idols on the Internet very often advertise this, which in turn arouses interest in their fans. Who of them is more vulnerable will show time, since they are all from different families and with different upbringing, and this is also an important factor. I think in a few years, gambling will be completely something normal and everyday in many countries, there remains only one question: will the state be ready for this and will there be help for those who suffered from gambling and at what level.
Yeah, when they see something from the people they are idolizing or when they are following someone over the internet, that person can attract the attention especially those young adults who are prone to hook on it and follow those influencers.
