Email sorting odds

Assume I have 65 emails in my Inbox, unfortunately a hugely invalid assumption. And now assume they’re sorted by date received. The probability of me re-sorting by a different, unrelated column (size, for example) and the items appearing in the same order is way less than the probability of you and I each selecting an atom at random from the universe and happening upon the same one.

If my Inbox is reduced to 13 items, then the probability increases noticeably. It’s more comparable to the odds of us each selecting the same living human at random.
