I agree! Gambling becomes a problem not just when money is lost, but when it starts hurting your life, affecting your daily routine in other ways. If it affects your health, job, or even relationships, then it's already a serious issue, even if you haven't lost much money.
It's about the impact on your life, not just your wallet.
It means that you are already an addict for you to allow gambling to be a threat to your peace of mind. This is the main reason why one needs to gamble responsible and stay healthy to avoid being addicted to gambling. Assuming, there is nothing like addiction and only losses when gambling, nobody will see gamblers as irresponsible people because they are still in control of your senses. Addiction takes over all your thinking mentality.
