How rare is a 3 Digit Account Username?

[123]

Obviously, 33 * 33 * 33 = 35.937 Accounts with a 3 Unit Username can exist at maximum.
Does anyone have any interest to buy or trade such an account? Is it worth to spend money on them, since these are kind of rare.

how is this related to cs:go and how is a steamID a user name?

It's not the Steam ID but the Account Login Username.
Not CS:GO related at all, but most of traders come from cs:go, why they could give me a reasonable answer to that

a digit is a number from 0 to 9.
nobody is caring about an account name it is private.

mines super low digit like that. Just means its a super old account.
