I am Capricorn, why is my personality more like Scorpio?

Constellation is not a definite thing, just like blood type, it is also O type, but it has different personalities. Think about it, if all Capricorn people have the same personality, it's unlikely, right? Therefore, constellations are only used by most people for reference, or they are simply invented, so some differences are nothing. Please accept it. I have a task. Thank you.
