I was advised and tool a class at our local Coimmunity college.
It was taught by experienced instructers who was used to beginning-starter students seeking Lath experience/training.
Would reccommend looking for this kind of help in your indeavor.

These little cheap Chinese lathes do an adequate job for the home hobby shop, most gunsmith work, and small projects as long as yo understand it’s limitations.
As @Peterson1 asked, do you live near a Community College that has course in basic machine work. Unless you have a friend/mentor that has a home shop and is willing to teach you the basics, that is your best bet.
I have taught several young men the Machinist Trade, but they all work for me. The best advice I instill in each one is while it is important to learn how to do things in a certain way, it is just as important to learn WHY you do things in a certain way.
I have said this before, so it is a re-run...
Learn to run it SAFELY. Lathes and milling machines are UNFORGIVING of careless or stupid operation.

I have one since 2019, I taught myself how to run it and later on chamber and thread barrels.
The dro quit 3 years in and I had to replace it with a newall, the durect replacement was discontinued.
1 time the half nuts wouldn't disengage and crashed into a barrel, it bent some gears, all of the replacement parts weren't drilled for the pins. And to learn the hard way, all of the parts I needed to replace appeared to be drilled by hand after they were assembled, none of them were centered or straight.
Besides that(which was probably my fault to begin with) I've had good luck, I've probably chambered 400 barrels and made numerous tools with it.
