If it's all gobbledygook to you, then you weren't the target audience.
Most developers are writing for developers who have approximately the same skill level and knowledge. The vast majority of tutorials out there are definitely not aimed at beginners. They're aimed at peers who know most of the same stuff, but want to broaden their horizons a little.
Now, if it were 95% easy to follow, and then there was one step that was only a few words long and made no sense at all, that would be the typical badly written tutorial. There are way too many tutorials that have a "rest of the owl" problem at some stage. I was trying to figure out how to do something today and I must have skimmed through 30 tutorials aimed at people roughly my skill level before I finally found one that explained the missing bit. That missing bit turned out to be pretty easy, but almost every thing I read just assumed people knew how to do that part, and focused in on all the wrong things.
As for actual tutorials for beginners, the biggest problem isn't that they're badly written. The biggest problem is that they don't exist. But, to be fair, they're actually really hard to write. Explaining things requires that you really understand them well. But, when you understand them well, it can be hard to put yourself in the shoes of someone who knows so little they don't even know what questions to ask. Most computerey things are complicated enough that by the time you feel confident enough to write a tutorial, you've forgotten what it was like to be a beginner.
