According to my understanding, the most idiotic PIN exactly is the one
with the highest probability of being guessed, in other words, the one
that is most often used by other people as well.
You are right in a mathematical sense, but you leave out the human
factor. If all people would choose their PINs freely, PINs for sure were
not equally distributed. 10% of the pins would be 1111, another 10%
1234, another 30% their owner's birthday and so on.

gives us an idea. I don't think the situation has changed much since
