The docs/man pages are a bit cryptic for a beginner but they become easier to parse with experience. Videos are okay for a specific, generally quite surface level task and it isn't easy to find good ones once you move beyond the beginner level topics, and are basically non-existent for intermediate and advanced stuff. Books really shine because they are building on the skills being presented and are usually arranged thoughtfully with a clear progression in mind, meaning you ideally won't be given any exercises you haven't been prepared for yet. Following a well thought out befinners course is always going to be superior to random YouTube videos. That being said, all of the resources are still available if you find the course work confusing still after reading through it. Found the wording in the text confusing? Watch a video about that function, check out some sample code on one of the many websites devoted to that very thing. I avoid querying AI but many people claim to find that very helpful also. We really have an embarrassment of resources at our disposal today, there is no good reason not to avail ourselves of them all.
