You get 2300 for betting $3 is a super lucky bet. You get lucky even if you don't often bet so you can really expect it won't happen in every 10 years. If you win again like going to a nearby shop and finding scratch tickets beside the cashier, you try for once and you still win big. There really is a big chance you have a fairy godmother following you all the time.
My experience could be called luck but not a huge win. I think I got $130 for betting $10. This is the biggest by far, it did happen again but smaller win and this is in sports betting. I think maybe 2 or 3 times a year.
