Because of this:

Let’s say X and Y are two numbers, where X is greater than Y.

Most of the time, X^Y is smaller than Y^X, as in these examples:

5^2 = 10, 2^5 = 32

10^2 = 100. 2^100 ~= 1267650600000000000000000000000 (ish)

So imagine taking an 8 character password from an alphabet of, say, 80 characters (26 lowercase letters + 26 uppercase letters + 10 digits + about 14 punctiation marks).

That’s 80^8 combinations.

But imagine taking only a 3 character password, but from an alphabet with 50,000 letters in it.

That’s 3^50 combinations.

It turns out that 3^50 is waaay bigger than 80^8 is. By a LOT.

And when you think of it, if you take a person with a 50,000 word English vocabulary, and ask them to cram 3 English words together, that’s essentially what you’re doing. 3 “letters” where each “letter” is taken from an “alphabet” of 50,000.
