I have a question for some of you mathematicians/statisticians out there.

It struck me when I read the latest thread by Famous Smoke that they are selling 1000 tickets to their raffle and will pick 5 winners. They are saying that's a 1 in 200 chance to win. Is that really the case?

It seems to me that the best odds are actually 1 in 996.

1st draw = 1 in 1000
2nd draw = 1 in 999
3rd draw = 1 in 998
4th draw = 1 in 997
5th draw = 1 in 996

Which is right, or are they actually equivalent in some way?
