Figure drawing design and invention by Michael Hampton is pretty good, coupled with the Anatomy for 3d books (there's one for anatomy and one just for the face) and maybe Mike Matessi's dynamic figure drawing book. Those are a pretty good intro to figure drawing and anatomy.
the two James Gurney books are very good, one for color and light, the other more general "how i work" but its pretty nice.
Scott robertson's how to draw and how to render are ok. A bit too convoluted sometimes. There's easier books on perspective and a lot of video material that not as far up its own ass as Robertson's. Not that its bad , he just likes to make simple things more complicated than need to. Perspective made easy by Estern Norling is a good start.
The framed ink books are also ok , i like them relating things to storytelling which is the whole point.
Keys to drawing by Bert Dortsons might be decent as a starting point.
Good recs, I'd like to add Constructive Anatomy by Bridgeman, pretty much everything that Andrew Loomis has put out, the Bargue Drawing Course, Jack Hamm Drawing the Head and Figure. These are all advanced and intermediate recommendations
As a beginner starting course I would recommend How to Draw Comics the Marvel Way and Perspective Made Easy. More important than any one book is to find art that you like and try to emulate what you like about it with your own characters and world.
The goal for a starting artist will be to 1.Have enough control to get lines placed where you want them accurately and 2.Be able to understand 3D forms (3.Have fun and be satisfied when something comes out nice).
As far as youtube channels go, I would recommend David Finch for rendering, Marco Bucci for color theory, FZDSCHOOL for industry design conventions, KienanLafferty for modern character design step by steps.

Additionally, one of the benefits of traditional art as a medium is the availability of affordable supplies. If you have the dosh then there's nothing wrong with using high quality materials however I would seriously recommend just buying a few reams of 3$ printer paper and working with that. Sketchbooks are good too but a lot of beginners don't take advantage of the whole page and can develop anxiety about needing to have a "perfect sketchbook".
If you are serious about working traditionally (e.g. not just limited by not having a tablet, wanting to "be a genuine mangaka") then you should invest in a G-nib or Hunt 102 pen and a decent No.2 brush along with bristol board and some Superblack or Ultradraw ink. NO HIGGENS
If you have a serious skill I would be willing to trade art lessons for lessons in whatever you do.
