I won $$$$$ on horse betting!!!

I never had much luck with... pretty much everything but I just made a bet on a horse through a horse betting site - I only put $20 but this time I tried this thing called 'trifecta' I had to get the first 3 horses right... so I made a $20 bet for... starting from my favourite number 7 - horse 7, horse 8 and 9... and voilà!!!! The horse betting odds were 82 to 1, so I made $20 X 82 = $1640!!! So here I am waiting for my first check from an online horse racing win... Infact, a first sports betting win ever in my life :) I guess they call this beginners' luck!
