For people who don't get it on your profile it says "(Your username) is a (your age) year old (your gender) in (Your Location) and is ranked (Your rank #) out of (Total # of users). Honestly I think the only people ranked under 1,000,000 are ghost players(accounts used to increase or decrease ratings in a game).
Patrick is correct. If you click on 'View all comments' on your profile then change the number in the address bar, it'll take you to an account, but the account is ranked somewhere in 300,000.
