It could become true, strangers things have happen, luck doesn't only happen to others :-)
You got your karma correct but there's a fault in your stars.
-You never actually gambled.Heck,you never opened a gambling site.
-You got whatever through the referral link which I suppose is unbelievable since you refrained from telling the website's name.
-Your story is too good to be true.Just my opinion.
The option of this being a story for superstitious people which will ask for his referral (since others won some
) isn't excluded either.
