That's unfortunately how it goes for a lot of people, and it sucks. Gambling addiction does ruin a lot of lives, and I don't see why someone gambling with Bitcoin instead of fiat should change this or make it impossible. I've seen a lot of people lose a lot of money and deeply regret it.
The first thing that I can say people gambling using bitcoin because the bitcoin is easy and instant. Ever online thing is good thats why people choose online rather than using fiat directly. Gambling addiction actually depends on yourselves and no one can't control you if you can hold just for a while it will be a great success
