No, when you buy games that have "Steam" or "Valve" on the back usually you have to install them and register the serial through Steam and it'll preload it on Steam for you and you play it through Steam Client. It's nothing more than a program that makes it more organized for you to play all Steam powered games instead of going in your program files list everywhere.
