Is 16 years old too late to start gymnastics?

I can do on my tramp a front flip, front handspring, front layout, back tuck, back layout, back hand spring, and round-off back handspring. On the ground I can do a back walkover and a front walkover and I can hold a hand stand for about 5 sec. I have always wanted to do gymnastics...is it too late? I can almost go down all the way in a front split. and I can do a scorpion. So is it too late??? I can also do a almost strait cartwheel
