Imagine if there were billions of unique First names and only 9,000 surnames and each person's surname was known only to that person and their bank. You and I may know each other's First name but unless I correctly guessed yir surname, I'd not be able to withdraw money from the bank. That's how the PIN works, the account number is the First name and the PIN is the surname.
