Is not vim a tool from an age of very much different terminals to what we have today, with different limitations that are no longer actual? Yearly(!) emergence of new tutorials trying to finally explain how to navigate with vim is a consequence of this disconnect.
In the end I find comparing vim to something like snowboarding or skateboarding intriguing. It doesn't matter how much you explain it, it won't be enough. You just have to try it out for yourself and see if you can get the hang of it. Once that initial step is done, that's when reading about all the intricacies becomes useful.
