Is 22 too old to start training in MMA in hopes of becoming a professional?

I already do a little bit of BJJ (only once per week because that is all I can afford right now....also the instructor also teaches us Judo moves). The BJJ is Gi as well so I would have to shift to No Gi. But is 22 too old to start in the other aspects as well? (I was thinking I would start training in either Muay Thai or Boxing). This is my dream (and has been for a while but could never afford to train. I have been told that I am a natural (naturally good posture when punching and kicking, good instincts on dodging and countering, and good at improvising if in a bad spot). I have sparred with a few guys for fun. I know it is nothing like competing but again...is 22 too old? (I would start my training then in a year or so I would go for my first amateur fight and build up a rep then move to a small pro organization and try to keep moving up).
