is like a 29 year old woman who has an angelic face and a fine voice to start a career as a pop singer and be successful?

There are probably at least 20 million women with angelic gaces and fine voices who want the same thing.

The odds of any of them making money off of music is next to nothing.

If you want to pursue a career in music, keep it as your Plan B.  Formulate a good, realistic Plan A that will pay you a living wage, and focus on that first.  Pursue music in your spare time.

Because almost certainly, it will be Plan A that puts a roof over your head and food in your belly. Whether you become a ticketed tradesperson or get a university degree.
