I started on drums when I was 25, self taught by ear. And bass when I was 42, also self teaching by ear. In my experience age has nothing to do with learning or becoming proficient at what you want to play. How much time and effort you put in has everything to do with it. The only thing that can stop you is self doubt.
As far as making money, I don't know because I've never had an interest in that, but learning, it can be done regardless of age.
