Now CNC doesn't make much money, but it's ok to make a living by technology.
I suggest you choose an industry and go deep into it. If you work for fifteen years, what else can't you do? Maybe you can't make money?
Let's just say that anyone who can learn, no matter how he learns, whether he finds a teacher or teaches himself, will eventually learn.
It's only a matter of time to see if you want to learn.
For example, a simple question can be learned by watching videos, or it can't be learned by watching videos. You need to recruit people to help you study for three or five days, and there will be a big gap in time. This is related to people, and there is a gap in people's learning ability.
The rest is the actual operation. You can find a factory as an apprentice for three years, or you can find someone who can practice to study.
However, I suggest you learn it first and see if you are interested.
