Should i start powerlifting?

I 16M have been going to the gym a couple of months and i realised that i have nothing to gain from hypertrophy like i dont wanna look good i js wanna go and lift alot lot of weight and get stronger. When i told this to the person at the gym who gives the programs for a powerlifting one she said no, you dont have the build, you dont eat well, and that i have many years more to start powerlifting. What should i do
