That is a fact about a gambling addict. They'll do everything in their capacity to feed their addiction and no amount of warnings will they listen to. And that's why it won't matter to them, someone who's concerned to them won't help at all anymore if they're already have something in mind which is common to them, and that's to gamble none other than that. A professional help is what they need to have because to avoid further mistakes and bad actions they do, that's all what they need to have.
Yes, same with alcohol addiction. There could be warning about drinking responsibly, but that's clearly ignored if the person wants to have a drink.
Same with gambling. People will see those warnings and simply ignore them.
I guess it's fine to have them, but not sure how effective these warnings really are. And maybe that's by design?, because there's so much money to be made in casinos, and I mean the owners, not the gamblers.
