To slow for my age?

Sup guys , so i’ve been playing baseball since a litte kid, cureently im 22 years old and still playing. (Not pro)

I’m a position player but i always wanted to be a pitcher so i decided to buy a radar gun to test my self.

I’ve been working on my mechanics and core workouts and my pitching velocity its always between 54 -58mph ( one time i top out 63 mph) according to my bushnell radar gun …thats what a 10 year old would throw!!!

Btw im a very athletic guy 5’8 ft tall and 165 pounds

HEEEEEELP I really hope my radar is the problem and might not be working properly lol
Or i’m i trash??
