It’s about the reference class. The class of allsame sequences has only a few members. The class of … random numbers all over ala 71833791 has a lot of members.

It’s about the reference class. The class of allsame sequences has only a few members. The class of … random numbers all over ala 71833791 has a lot of members. So the probability of seeing the former class is tiny. Think of it in terms of coin tosses. Two heads is less likely than a head and a tail, because there are two sequences, 10, and 01, that map to the class of having one tail and one head. But there is only a single sequence of 00 in the class of all heads.
