I am hoping that people who gamble can still prevent themselves from being addicted on it, there are still a lot of things that we can do to prevent addiction and those gambling websites or application can also help their customer by doing these things.
1. They can use more secured ways to identify the real identity of their customer, the best thing to do here, aside from valid ID is they should add "take a selfie" on identity process.
2. They can also set a time limit of playing for a player, give notification if this would be their last game anymore for today.
3. Set a notification showing how long they've been playing.
With these kind of features, they might actually help or lessen the addiction of a gambler.
If the casino implement all this criteria, they'll run out of business to other casino that don't have this restrictions. Gamblers don't like to be told what to do and if you try telling them, you'll lose a customer and they make tell their friends not to use your casino anymore.
It's not the duty of the online casino to prevent underage gambling or gambling addiction. We're responsible for that and if as a parent you don't know the online activities of your kids, that's your problem and not that of the online casinos just offering a service.
I'll agree with your verification process to be implemented on all online casino that are asking for KYC verification before their customers can use their platforms. This will help reduced underage betting to some extent but don't forget casino accounts can be bought.
