Just for fun, I did some quick math. Assuming each digit could be either a numeral (excluding zero) or a letter from A-Z, that's 35 possibilities in each of the 3 positions. So the odds of matching the 3 digits in exact order is 1 in 42875. Happy to be corrected if my math is wrong!

In my opinion you can not mix up the digits and letters into the same pot.
So there are 9 possibilities for a numeral (exluding zero) and 26 possibilities for each of the following letters.
Therefore the probability is 1/9 * 1/26 * 1/26 = 1/6084 =~ 0.000164
