Some times young ppl & adults become addicted because they've made small bets for enjoyment. It doesn't take long for ppl to become addicted so they've got to be careful because many ppl don't realise when they're addicted. Students shouldn't focus on gambling they've got to concentrate in studies & their future.
I also think it's a subjective thing, whether a student plays or not always depends on him, they have no excuses.
There are a lot of kids who get into the game even though they are studious or people who are very good at school, so in my opinion it's just subjective.
