"One in a million" is an informal expression used to describe something or someone that is incredibly unique, special, or rare. The singer says "I was gonna be that one in a million" to state his intentions to be special and different from everyone else. Ex: My grandmother made my prom dress. It's one in a million. Ex: I'm thankful to my professor for helping me with my thesis. He's one in a million.
