Whatever the kids see to their parents, they're going to imitate it while they're young. And what's even harder is when they develop that habit until they grow up and that's the hardest part when they're already aged and can't removed that habit of gambling. All of the blame will go to the parents for not noticing that but I doubt it that they can't noticed that because when they're too stressed with what they're doing, they are not giving time to their kids and have some family time. That's why gadgets and stuff should have a screen time and limit for their kids to get monitored on what they do with it.
Because if they're going to give such limits, the kids that are seeing your actions as you gamble will also be dealt into addiction as they grow old and out of curiosity when they try to run an app of a casino and managed to see that you've got money there, they'll start to have that in mind that they can easily make money from it. But for them in order to make money, they need to steal money from their parents and have it deposited to that casino so they can start playing and making money. You know that the minds of the kids nowadays are tricky and innocent, they think what is right is right but on top of that, what they think is right is actually wrong and they're justifying it and dying to argue with what they believe is okay and right.
