Is it too late to learn theory/music composition?

Come on mate, you're 19 . . . it's never too late!

Yea plus 1 to that! I'm 28 and only started learning piano and music theory this year. I'm a sample based producer and all my other songs have been made from sampling. I still decided to learn piano because it gives me far more options in this age of midi...
