Young students who get pocket money from parents shouldn't think about gambling. In poor countries parent can't educate children with out suffering. If they start gambling they'll betray their parents it isn't fair they've got to graduate & help their family.
it is through that parents in developing countries need to suffer more and work extra when compared to people in developed countries to get their children education, in the end it is about giving one's children what it is the best for them and send them to a university so they can become highly skilled professionals in the future.
I dont know if the case of a student partaking in gambling could be considered to be treason in some way towards their parents, I would not use that word slightly.
I would be something equivalent to treachery of their children actively stole money from them in order to gamble or bet on casinos or betting house which do not enforce the minimum age required to access to their services. That is a completely different scenario.
So far, if a kid is gambling with money it was given to them to do whatever they wanted, I would just say they are just losing their path and need to be corrected so they wont get addicted to gambling and actually get involved on stealing money from their family.
