c. or you are a superstitions gambler, when you have signs like losing 3 straight in a row, then you quit because you know that you're having a bad luck
This one doesn’t necessarily mean that you are superstitious. It still is logical to me because losing three times in a row must affect you somehow and so if you’ve lost then you should take a break for a while and collect yourself. You might end up too frustrated after losing consecutively so better to take some time off.
