So the question is, "Is there really no way out for gamblers to stay fit and in control?" Is gambling addiction inevitable?? If winning and losing lead to addiction, how can we maintain our sanity?

Why would you jump to that conclusion. And why would it always lead to addiction? Majority of people can use substances, watch tv, gamble, eat sugar or do anything addictive, without getting addicted.
But people are different and if you happen to have addictive personality that gets easily hooked, ADHD or something else, you might get addicted more easily, as your dopamine system isn't working in healthy way.
