This is assuming that each individual fortune cookie made has a unique set of numbers and fortunes. They most certainly do not go through that much effort to ensure randomness when printing the tags, they’re likely printed in batches of 10,000+ with all the same content and put into cookies, then the cookies are mixed before shipping to ensure random fortunes per shipped box. So the actual chances of a matching number are significantly lower considering there might only be ~100000 or less different combos of lottery numbers in the nationwide cookie supply of 8 billion.

What this does mean is that if a batch of fortune cookies did just just so happen to land on the jackpot numbers for a big lottery, you’d likely see a record number of jackpot winners and it would trigger some level of investigation into who got those numbers and how the fortune cookie companies pick them.
