I am not a gambler. But I have bought the odd scratch ticket/lotto ticket/casino... uh chips I guess, since it's been legal for me to do so. I have never won anything. Maybe 20 or so scratch tickets, 4 or 5 lottery tickets, 10 or so
Proline tickets. 50 bucks or so in casinos. Never won a dime. Hell, I've even put in for some of those one-in-three odds of winning heart and stroke lottery tickets. Like I said, I'm no gambler, I could call it quits if I did win, but I seem to be struck with shit luck on draws so that hasn't really ever come up!
e: my parents furnished our first house with lottery winnings. They won like 3rd prize or something (4/6 on lotto 6/49 I think but I would have to ask to be sure).
