XCB (X protocol C-language Binding) is a library implementing the client side of the X11 display server protocol. XCB is written in the C programming language and distributed under the MIT License. The project was started in 2001 by Bart Massey and aimed to replace Xlib.

XCB was designed as a smaller, modernized replacement for Xlib, previously the primary C library for communicating with the X window system, coinciding with a complete overhaul of the X implementation that took place during the early 2000s.[1] The main goals of XCB are to:
- reduce library size and complexity.
- provide direct access to the X11 protocol.

I'm an XCB beginner too, but my knowledge and videos are based on experience, research, trial, and error. I believe in teaching a subject while I am a beginner because a beginner won't skip details and will explain the subject more beginner-friendly way than a professional at the cost of potential loss of accuracy and rigor. the struggle of learning is still fresh on a beginner's mind. Finally am learning more by teaching and am learning better code and asking more questions because I know someone will read my code and watch my video : )
TLDR: A beginner understands beginners more than an expert and teaching is a suitable learning method.
