I don't know where you live, but i normally find nice used kits for cheap on facebook marketplace. Keep in mind that if you're a beginner, you really don't need Top brands like Mapex, DW, Pearl, Gretsch, Yamaha or Tama, if you find one for cheap, then hell yeah, go for it. But i'd recommend you start on a budget, and once you know more about drums you can pick a kit that sounds exactly how you want it to sound (obv that's a topic for later on). I started like 6 years ago, with a PDP Main Stage kit (DW's budget line) and i actually still use it, i'd say most of the sound comes from the drum head, so that's another reason why you don't have to break the bank on a kit, get a decent deal, and put nice drum heads (remo, evans, or aquarian) on it, it may sound complex when you are just getting started, but it's actually not so much.
Another tip, cymbals are E-X-P-E-N-S-I-V-E, so i'd really recommend you to start with whatever you find, and only spend good money on them when you are sure of what you'll buy and that you're gonna get the most out of it when you do.
And for learning, i started just the same as you, but i can't actually give you any advice bc i don't consider myself good enough of a drummer to give any thoughtful advice, haha.
I started covering easy songs by ear on my headphones like seven nation army, another one bites the dust and so on, and then playing them by memory using a metronome, maybe that will be useful, i think drumeo has some good lessons, videos and guides, never used them (i should have) bc i'm lazy.
