It's never too late to play. I've shared some of my work in the past. I'm a classical guitarist by training, though I've been paid to perform pretty much anything but classical guitar. There was a period in my life when I needed the money. It didn't pay well, but it fit into my schedule, or could be forced to fit into my schedule. I'd eventually no longer need the money, but I kept performing.
I'm now more or less retired. It has been a little bit, as some aspects of my life are kept private, but I have a band that is willing to let me come sit a few sets whenever I want.
