Winning is alway the mindset of a gambler. They are always optimist that even they have 1% of winning they will still take that chance to win.
Though sometimes they tend to be greedy, they wont stop even they already loose huge amount of money, likewise even they already won they still wont stop.
But it is natural. Not every time it is greed but yes like every other human is likely to get wining moments in such times, same the gamblers are doing. But the matter comes, when they already know that this game would make their money gone, they will lose all what they have. Still they are ready to go in and take the part. And when they lose, their regrets are so louder and solid but all in vain.
That's the biggest part of it, regretting when you already lose everything, for sure gamblers that is too engaged forget about limiting bankroll,
when times that they already some luck winning from the game instead of quitting they keep proceeding, thinking that it will bring more bacon
for them, but the end will be just the same, losing and regretting after.
