I’ll give you some suggestions you can download for free from the internet archive

As others have said, The natural way to draw is an excellent book https://archive.org/details/naturalwaytodraw0000kimo_q8c1

Andrew Loomis has a lot of great books.

Personally I recommend Fun with a pencil. https://archive.org/details/andrewloomisfunwithapencil1 You can start from cero with that one.
He is good for anatomy and portaiture

Anatomy for the artist by Sarah Simblet This book has great photos, even to just flip through

This next book I haven’t read myself but is a very important topic!! Some people are scared of perspective because it looks very technical, but it’s not hard at all. You definitely should get comfortable with it!

Color and light by James Gourney This one is more about painting, but these are concepts that you should get familiar with early on, and some people neglect.

Now for video:

The Proko channel on youtube has great tutorials on anatomy as well, I used those a lot arround 2014? So I would look through their archive.

For figure drawing sessions

The Croquis café https://croquis.cafe/ Has a huge archive of natural figure drawing videos and photos, you have to pay a subscription to access but it’s so worth it! They have a free section as well if I remember correctly

Edit:

For materials, start simple: pencil and paper. A cheap sketchbook of just printer paper will do. Whatever you have arround .

And just draw draw draw every day! a little every day will do wonders for you. Don’t be precious with your drawings, and learn to let go of your mistakes and your successes as well.

Check the different resouces and see what clicks for you. Art requires you to pay attention to a lot of stuff, but don’t get overwhelmed. Ask for advice, look for drawing groups/ buddies. Have fun with it.
