Depending on how you count, famous numbers isn't exactly a well defined category, the number of special sequences will be less than 100 and certainly less than 1000. Regardless, very small compared to the overall number of sequences.
Let’s assume that there are on average 2 lottery drawings per week per country, which means c400 lotteries.
So 400/150000 = 1/375 chance per week, so it’s going to happen every 10 or so years.
The U.K. has 7 draws per week, and I assume the USA has draws in every state, so it could add up fast. I’m assuming most lotteries are weekly, but they could be much more infrequent.
I assume there are other funky possibilities like the crazy thought that someone could get their own phone number as a result, or the sequence 10,20,30,40,50,60 etc so I suspect there are a few other notable sequences hidden in there.
EDIT: Oh, the best part: we have this "lottery for the impatient" that has draws every 4 minutes :)
