It is a sign of being addicted in gambling. I honestly got the same experience of it before but not too much, as I remember it happened to me only two times, I had a weekly campaign that I joined before and after I got payed every week I spend it all on gambling after I lose all of it in that week, and bet again the other week with a thought that I will recover what I had lose, but ends up losing all of it
That is the natural response that we could have after we lost in gambling, who would have decided to continue after he lost his money, of course he would think of it first before making an action, but mostly no matter how much your brain or instinct tells you not to, but in the end you'll find yourself betting again, there is no doubt about it. But the best thing that you could do is to quit it and forget the rumors that you could make easy money in gambling.
