ELI5: Got an extra ticket?

Can anyone explain the guys outside of sporting stadiums asking for an extra ticket? Do they want to buy any extra tickets then sell it or do they want to go to a game for free? I live in Chicago and this happens outside every stadium by I never worked up the courage to ask these guys what exactly is their end game.

They are scalpers. They just cant say "Selling tickets" but they can say "Do you have any tickets?". Sometimes they will hold up signs that say "I need tickets" Which really means they have tickets to sell.
