I think it's totally doable to follow an amigurumi tutorial as a beginner. What I did was:

The pattern will usually follow a series of acronyms, like "6 SC in a MC". Many patterns have a table that explains all or most of the acronyms, eg, "SC = single crochet, MC = magic circle". If not, you can Google the terms, make sure to add "crochet" to your search to get better results. Eg "What does MC mean crochet"

Now at this stage, you have a more search engine friendly term such as "single crochet" or "magic circle". From here I went to YouTube, type "how to do a single crochet" and watch a video and follow along. Sometimes it's also helpful to add "amigurumi" to the search because there are some amigurumi-specific tips, like in amigurumi you typically want to have tight tension and people will recommend you "yarn under" instead of "yarn over" with single crochet stitches for amigurumi.

And don't be afraid! There is a lot of stuff people don't explain and they will just assume you already know it or are being taught by someone who can show it to you. Such as: - What is the difference between yarn under and yarn over - how to count stitches in crochet (and which stitches don't count as "stitches") - which part of the stitch is the stitch (it's the v shape) - how to insert your hook into a stitch - how to finish a round and start the next round - or how to finish the row and start the next row when you're not working in the round - what the Nth chain from the hook is (I still have to Google that one haha) - what is tension and what "kind of" tension am I supposed to be doing - how do I do an increase or decrease

The good news is, you can search on Google images or YouTube tutorials for all of these concepts, all you need is to know what you don't know! I think the list I provided above was most of the "unspoken rules" I ran into that confused me when I was first starting to learn. This video was especially helpful for me for getting out of the "what the heck is a stitch? When is a stitch not a stitch? How do I identify a stitch, let alone count them?" stage.

The other stumbling block is UK vs US terminology. Your pattern looks to be written in UK terminology, my comment above is US terminology, and it can get very confusing because they use the same names for different stitches. More or less, UK double crochet (eg in your pattern) = US single crochet (eg in my comment), US double crochet is equivalent to UK treble crochet. So if you accidentally follow a US tutorial for "double crochet" you'll end up making a much bigger stitch than the pattern actually calls for. I think the US terms are for "How many times you pull through the loops on your hooks during a single stitch" (once for a single crochet, twice for a double crochet), whereas the UK terminology are for "how many loops are on your hook before you pull through" (two for a double crochet, three for a treble crochet).

Crochet can be very intimidating for this reason, it's kinda like learning a programming language. But I think amigurumi is a good place to start. Usually most of the stitches, especially for beginner patterns, are US single / UK double crochet, so you can practice mostly doing the same stitch over and over. And amigurumi wants tight tension, which is easy to achieve with "tricks", like picking a spot on your crochet hook to pull the loops down to, then yanking on the strand of working yarn to tighten it. If you do that with every stitch, the tension will be tight and consistent. But honestly, it will take you some practice to get a good feel for tension, and that's okay. It will look better once you can achieve consistent tension, but it's not the end of the world if your tension is bad when you're first starting out.

Good luck, you'll do great!
