I like some of Tubal Cain's vids as well. Old shop teacher. Still pretty "old school" too by the looks of it. Nothing at all wrong with that - start at the basics!!

My High School Metal Shop Teacher was the best.
Mr. Wade was one of the best. To me, he was a hero.
I wish I could go back and thank him proper. By the time I was a senior, I was his TA in two classes
 
This is the video you want to watch to learn about cutting edge angles.
 
Ditto on what you folks have said regarding Quinn's channel Blondihacks. She is an outstanding teacher, I have learned a lot from her videos. All of this is new to me, now in the process of setting up a new Grizzly G4000 9x19 lathe.

Content on the LMS web site is also super helpful, check this link for info on the tool bit differences: https://littlemachineshop.com/info/turning_tools.php

I made up this little chart to help me understand it better, comments welcome:
