Another channel I've been watching a lot of is
Black Magic Craft who scratch builds a lot of foam terrain pieces. I like some of his videos because with the right tools, he can crank out great setting pieces really quickly, but he makes a point of showing you how to do a lot without the expensive tools like the hot wire table. Yeah, it's fast to do with the expensive toys—and for some stuff you really need the right tools or it's just not going to be practical—but so much can be done with so little…
Of course, my issue with Black Magic Crafting is his painting style—he does everything in shades of black.

But the HQ furniture painted with mostly washes shows what can be done with inks and washes if you want your colors to pop a bit more.
It's all techniques to pick up, try when you get the chance, and use what you like and what matches your skills (which will improve with practice I'm just about positive, says the guy who hasn't committed to buying a bunch of paints and whatnot yet.)
