Heck, I've also seen kids here in our community that are gambling already (both physical and online), and the range of their ages are between 13-16. I asked them if where they are getting those money and it's from their parents. World really is getting worse, and worse and like you said, it's going crazy.
Who is to be blamed in this situation? Without a second thought, I would blame the parents for allowing them to do all of that, and on top of that, they are giving these teenagers so much money without asking them what they are spending the money on. What kind of parenting is that? You can be careless as a person but you can't be careless as a parent because that will ruin the future of your children if you don't bring them up by teaching them certain things and disciplining them on certain matters.
A bad parent is the reason why we see bad children in society today. If parents keep an eye on their children, watch their activities and make sure that they aren't involved in things that aren't good for them, we won't see these kids doing all these things at ages where they should be focusing on their studies.
