Fortune cookie lottery numbers

I just saw someone extract that little slip of paper from a fortune cookie and it got me thinking, are the lottery numbers that appear on the reverse side randomly generated, and if so, do they properly cover the right range of numbers. It's conceivable that there is just a set of 100 or so fortune messages and that each of those is assigned to a specific sequence of lottery numbers (so that there is only a set of 100 or so combinations that would ever appear on a fortune cookie). If that's the case, then ever playing those numbers would be a bad idea because you'd have a good chance of having to share the prize with other cookie eaters.

One news article from 2005 seems to imply that the numbers are shared, but the way it's written it's not entirely clear.

Anyone out there have a reference to how the fortune cookie lottery numbers are generated?
