I believe it's a generational thing. We, in our late thirties, didn't have so much video content, we studied from books, learned from written content. Younger generations adapted to use videos as a learning aid, sometimes as the main learning platform. We won't ever be able to understand how they work. Their brain just adapted to this kind of learning medium.
For me video talking about code is slow, unsearchable, unskimmable. I cannot easily go back to more difficult parts and reread (watch) them at my own pace. I cannot use them as a quick reference. Even my photographic memory doesn't work with videos, there's just something more powerful with black on white words and formulas.
Also completely agree about youtuber credibility. Being easy going, with good lighting, nice looks and neat surroundings makes them sound authoritative on the subject they talk about, especially to the newcomer ears, without any real backing.
