Honestly, I find it complicated. Just looking at blockchain activity to decide if someone is addicted to gambling isn’t a solid reference. Anyone can make lots of gambling transactions or play regularly, yet still not consider themselves addicted.
For me, addiction is more about the outcome - how a person reacts and behaves because of gambling. That’s why I think trying to regulate “gambling addiction” this way is useless. Either the government bans gambling completely and punishes violators, or they just let people gamble and accept it as it is.
It's true that anyone can gamble frequently, even if access may be complicated or difficult. However, those who truly want to gamble will certainly find a way to do so. The more transactions they make or the more frequent they gamble, the less likely they are to admit they're addicted. I believe that people who are blinded by winning at gambling don't care about anything other than gambling.
It's difficult to get the government to ban or restrict gambling, or anything else; it's more a matter of individual awareness.
