It is easier to think you are going to act in a certain way when you have no money, but huge and unexpected money can bring out a side of you that you never expected to see the light of day.

I have not recently won any huge money from gambling, but when you win big, there are chances of you becoming more reckless with gambling because you believe you now have enough money to risk gambling. It is the wrong reaction from a gambler, unless they don't need the money won, because a wise gambler should maintain their stake, while using the money won to pursue other investments outside gambling that will be beneficial.
