Could i make alot of money as a sports manager for a pro athelete?

I am in 15 & i basically grew up around football because my brothers played it. I developed a love for it & i want to be a sports magager ; making the amount of money that Tasha Mack from the game makes. My question is could i ever get that far as a Tasha Mack level sports manager? I want to manage athletes & work with endorsement deals for them such as, Nike, Gatorade, & others. Does anybody think that i will be able to ban as much as Tasha? & hoe much does the professional athlete manager make?
