Do what the other anons said, just type 'vimtutor' in your terminal and do the interactive tutorial. It will teach you in half an hour all that these soy-dripping websites do for free, plus you can run in on a potato without internet access and you don't get your browser data harvested.
After that you can start using Vim and read the user manual bit by bit. Don't try to read it back to cover, read a bit, use Vim a bit, read a bit, use Vim a bit, and so on. To access the manual type ':help' in Vim. The manual has roughly to parts: the actual user manual and the reference documentation. The reference goes into detail and is intended for people who know what they are doing. Read the actual user manual instead.
I find these video counter-productive. Just do the tutorial yourself. The video format is better suited for short "tips" style videos, but YouTubers have to make 10+ minute long videos for that sweet advertising money.
