They're not. Not a kata issue.

Why are they saying that if the PIN contains letters, that it should return false no matter the length, when you could just accept int instead of string? IRL when you go to an ATM it'll only have numbers on the keypad, and if you look on the website, if you try to put a letter instead of a number, it'll just not allow right?
