Am I too young to realize that fatherhood isn't for me?

Am I (19M, soon to be 20 on January 28th) too young to understand that fatherhood isn't for me? I recently came to the realization that fatherhood isn't exactly what I want to pursue in life, because I'll be brutally honest, I'm not financially, and most definitely not mentally equipped to have any children. I have a plethora of other reasons why I don't want kids, but one of the main reasons why is because I know I would be a horrible father. So I'll do both me, my potential future partner, as well as my (permanently) non-existent children a favor by abandoning the idea of becoming a father entirely. I know that I'm quite young to realize this, and I'll understand if you guys tell me that I know too much for my age. I'd love to hear your responses either way though.
