Yes - that statement is true in one sense, but the gambling industry is also given the responsibility to prevent more irresponsible gamblers in several ways. They know that gamblers will eventually become addicted - they know the profits they will make will be very high, but they also don't want to state out loud that their target market is irresponsible gamblers.

Almost all casinos will advise their customers to gamble responsibly and wisely. This advice is written on their website - but have you ever find a casino intentionally block you just because you're consistently losing? So what's wrong here? I don't think the casino is to blame, as it's the gambler's responsibility to gamble responsibly.
