Am I too old to start gymnastics?

I'm 11 and i can do front flip and almost a back flip on the trampoline. I can do a right leg split. and a back bend. i can do obviously a cartwheel. and a handstand. and a headstand... I did dance for 3 years but after i got into x-cel (junior competitive dance) i didnt like it anymore especcialy my dance teachers. I got bored. And sick of it. I stretch every morning too. And i know that most people start at like 2/3 and like 4 and stuff so i dont know.. Theres a gym about 40 minutes away from my house. My great aunt ( i think) does gymnastics. And is really really good. Shes been to the olympics and nationals and stuff. I am pretty small for my age... Smaller than most people in the same grade at my school... So yep. But i think i am too old to start it becuase as i said most people start at 2/3. either way i would be in recreational. and also this gym goes up to 18 yrs old. please be specific if there is anything else i need to learn and stuff lol
