A few things

[Adrianis]

You won't be a good programmer by doing tutorials, watching videos and so on and so on ... Buy a book, read it, solve the exercises and start a few projects

Depends how good the tutorials are, and video tutorials can be of very high quality. You may need to do some looking, but in my experience there has always been a quality tutorial out there on any subject and for any topic. You can absolutely become a good programmer, a good artist etc by doing tutorials. You just need some serious self-motivation

What's the point in having 100 custom stories that have no story?

The point is that people enjoy making them. There are many good programmers and artists that want to show off their skill, but they have to work on their own, they can't do story so to hell with it, make it anyway. There's still much to be gained for them personally
