For the average person, is it too late when they reach a certain age to become a great instrumentalist and make their own well-received music?
I would have to say no.
Going off of what Lensherr said, it should be a want and not something you're forcing yourself to do.
Once you learn an instrument or learn how to use a music studio (such as FL Studio or Ableton Live), mess around with chords and notes and what not.
Find what sounds good to you, and experiment a bunch.
~Should be able to come up with something pretty awesome
