Students will not become targets, they will only spend a little of their money. But what is concerning is that the habit of gambling at that age is very vulnerable. If they cannot stop, they may gamble worse when they start earning money from a job.
Emotionally, students are also not yet in control. It is feared that they will be affected by the desire to gamble and may harm fellow students or others. They may not be able to visit physical casinos. But online, they can access gambling even with a little of their pocket money.
Students do not have any source of income due to which they can use their spare money for gambling but it will not be very big. But here when they win some money then their greed will increase and they will consider gambling as a good place to earn money. They may not get much money from their parents for their daily expenses but when they suddenly get something from gambling then it will make them very excited and they will become addicted to gambling. No one is addicted to gambling in the beginning. They get addicted gradually and those who fall into this trap will have their career in danger while they are students. This is because they will be busy with gambling instead of studying.
That is what is concerning. I believe casinos will never specifically target students for gambling because they do not have income sources that would benefit casinos. However, the gambling that students engage in is very risky. If they do not become addicted to gambling while they are still students, it is highly likely that once they graduate and get a job, they could have more insane gambling activities with the money they earn themselves.
