Also funny dad jokes.
FWIW It's a TV show (slash media franchise; see: https://www.americastestkitchen.com/ ) that happens to have a YT channel. I primarily know it from PBS.
Once you have some basics, YouTube is just a fantastic resource in general for things like knife skills, or breaking down subprimal cuts of beef, or if you want to see a bunch of different takes on making a bouquet garni (which in a cookbook will frequently be succinctly "tie it up in a leek leaf") or tying a roast.

Anyway, as long as we're making suggestions, my two favorite dessert books are
The Cake Bible, Rose Levy Beranbaum. Had it for at least 30 years and was one of the first cookbooks I ever bought.
Classic Home Desserts, Richard Sax. Borrowed from a friend and after she warned me not to get anything on it (was one of her favorites), I got my own copy. Still in frequent use 25 years later.
1. On Food and Cooking: The Science and Lore of the Kitchen by Harold McGee. Not strictly a cooking book in the sense of recipes, but the most exhaustive encyclopedia / intro into the science and mechanics of cooking
2. Modernist Cuisine: The Art and Science of Cooking. The previous, but written with a "more is more" approach and an extra focus on modern techniques. More details, more pictures, (much) more volume and much pricier.
3. Serious eats Food Lab - Probably the best resource on "why/how" a given recipe / technique works that's accessible for free on the internet. I think the main author of this (J. Kenji Lopez-Alt) is also co-author of one part of the Modernist Cuisine.
4. Good Eats by Alton Brown. This used to be a TV show running for well over a decade. Alton Brown usually tries to do one recipe / technique / ingredient per episode and explain as much as he can in 30min or so. The first episodes / seasons are a bit dated (I think he goes over some of the older stuff in his later seasons), but overall probably the best TV show on cooking I ever saw.
5. America's Test Kitchen - a youtube channel. This is a bit of a mixed bag, but when it comes to a channel that I'd recomend to a beginner, I'd probably start with this. Second would probably be someone like some of the Adam Ragusea older episodes (I think he lately went into body buliding a bit too much), or some of the older stuff from "@FrenchGuyCooking" (I got to him through a video done by @ThisOldTony).
6. For recipes : personally I go for David Lebovitz. Old SF cook who moved to Paris some decades ago and at some point used to publish a lot of recipes on his website (though I have the impression he lately pivoted into more of restaurants reviews / social media, the archive is still good).
