We all know that gambling itself is addictive. That means, no matter what happens, it can lead someone into an addiction. The overall role of gambling platforms is to make the players stay and play more; the reward systems, marketing strategies, and even the UI/UX are optimized to make players stay, and that's another contributor to the addiction.
There's really no way out, and if someone is really not addicted, they could easily stop; if not, then there's a problem. Control should be there to make sure that you don't get over the line.
