Gambling is addicting because of the greed of wanting more and more. It's never going to be good enough.
You will be needing money until the day that you die. The amount of money is never going to be enough for all the things that you want, unless you're a millionaire, then you have it all.
Even if you are millionaire, you would still be greedy enough to make another millionaire. If you don't want to lose your money, you should not be greedy in gambling and use money that you can afford to lose to bet.
