Sometimes having a lucky win can be very scary, you know how slim the chances are of winning especially when it's a big odd, for some people winning from such might be a trigger to continue gambling while others might decide to take a break. As for me whenever I win I always slow it down for a while because I know that there's a high chance of losing everything my profit if I'm not careful
Same here, I often have this mindset that the best thing to do after hitting a big win would be to first retreat for a few days before gambling again, reasons because I usually feel like the casino must've noticed my win and might be keeping an eye on me, seeking for an opportunity to take back what they've given me, and this makes me super careful by retreating and focusing on different sources of recreation.
Again, huge wins usually releases some sort of dopamine in a gambler and opens their mind to endless possibilities of winning even more wins and as we already know, this can potentially lead to unintended losses.
