Its called reading books and scavenging documentation. Youtube (or Vimeo, or 10,000 other sites) is completely free, and what money is possibly earned from it is very little. If someone made a video tutorial about how to make a game, baby-stepping you all along through programming and content (which I haven't heard of, as it would take VERY long to create such a thing, time is expensive for a skilled programmer), why would they offer it up for free on the internet, thus wasting time worth $2400 (programmer earns 60k a year, $30 per hour, takes 2 weeks to make a pong or tic-tac-toe tutorial series, probably), and not earning anything off of it. Yes, there are great videos on varied subjects, but they are usually contributed freely by experienced (and unexperienced) people with no intent on giving you a Grade A curriculum on Youtube for free, but rather enjoy teaching sometimes on certain subjects. For example, I am sure if Dennis Ritchie and Brian Khernigan were creating C in this era, they would not make a Youtube channel off of it, but write a book, as they did. The book probably made more money than their Bell Laboratory salaries (I would assume, I have no facts to back that up, but it is almost obvious). That book is called The C Programming Language, and I would very much recommend it to you.

EDIT: I am sure you will run into programming tutorial series (*cough* The New Boston *cough*), however these are usually not of good quality (*cough* The New Boston *cough*). Books are edited to the teeth by an arsenal of competent and experienced professionals, videos are made in a garage by a hobbyist.

EDIT#2: I am not trying to criticize or chastise you, your questions are in a league with Einstein's compared to mine back on the old mailing lists and such.

I have a complete series where I build a memory match game from scratch:
