Is the photographer worth the investment?

It's hard to do it without experience. . Photography is a big investment. I suggest you accumulate it for a few more years.

At this stage, you can download some books and learn some basic knowledge yourself.

Education is not a problem, don't worry, there is no conflict between vocational qualification certificate and education certificate. It is recommended to apply to the labor department and study through formal channels. If you pass the exam, the state will issue a photographer qualification certificate. Don't give money to these private units, will they give you a certificate?
