A relative of mine is a big fan of The Woobles, they got me a panda kit that I really have to start on. But the how-to videos go over every step in detail and are pretty easy to understand.
The Woobles are a little pricey, but having that kind of cute project and video help can be a good motivator. I think starting with amigurumi can still be a little ambitious though. I’d suggest starting with a blanket of single crochets to get comfortable with the hook - all you need is the right size hook and yarn. No need to spend more than $6 at Walmart or Dollar Tree.
The good thing with blankets is that the size is whatever you want it to be. Just stop making your chain when you get one dimension right, and then finish with whatever row makes you happy. A single skein of the cheap SuperSaver/RedHeart can make ~8 sq. feet of area - a nice 2’ x 4’ baby blanket is a good size for a beginner. Blankets are also very forgiving of fuck-ups - which in crochet is usually forgetting a count (as a stoner, this is usually why I knit)
Single crochet is a stitch type. Crochet is about making chains, and then doing different stitches back into the chain. Single crochet is the most basic stitch. (There’s also double/triple/half-double, but these mean different things depending on where you are from).
You could always go find whatever bottle my mother crawled into and dump her out. She probably won't teach you how to crochet since she's old AF but it'd be funny.
Get a skein of medium-weight yarn in a light color (it's easier to see what you're doing) and whatever the recommend hook size it says on the label. Then watch some tutorials for basic stitches. I'd start making a little pot holder kinda thing with double or half-double crochet stitch. It's small enough that you can get used to turning rows, and it'll work up pretty fast with the medium weight yarn to give you some nice dopamine when you finish.
I would definitely recommended learning with just regular yarn, nothing fancy, until you get used to it. Yarn with lots of variability in the weight (as i expect plastic bags would have) is going to be difficult if you're not comfortable with the basics.
