No, it does a pretty good job of showing you the base mechanics. And as a player you can take time to practice them (which I did). But there's also just a lot of things you don't know about the world and the mechanics yet that you learn over time. There's a difference between picking them up and mastering them. Or are you trying to say that from the moment you left the Plateau you were already a perfect master of all combat skills and never got better as a player in the slightest throughout the rest of the entire game?
Well...I guess, yeah? Because they're incredibly basic. This is the beginning basic stuff you learn when you're first starting to game. It's so basic that, despite the game never teaching me about a lot of it, I learned it by accident. Take flurry rush for example.
Back in OoT, when I was 6 years old, I had to dodge enemies, block their attacks, and look for openings all on my own. Take for example a stalfos, very basic enemy you meet early on. It defends itself and you need to find openings to attack. Blocking will help you study its behavior, but won't give you much of an opportunity to attack. You can trade with a stalfos, but this is a bad idea in the long run. What you need to do is figure out at what point is a stalfos vulnerable in each of its attacks, you must then figure out what attack it's going to use, you must then use the appropriate attack to damage it without trading. You can also try to use techniques to lure it into certain attacks and you will become more aware of these as you progress through the game.
In BOTW you dodge....and that's it. The game then forces an opening for you and allows you to wail on a defenseless enemy. Again, I kinda find this to be patronizing. Every time it happens, it feels like there's a very excited preschool teacher clapping loudly in my ears saying "YES! YES! GOOD JOB YOU DID IT! 2 + 2 = 4! YAY!". This is always easy, and the only thing that changes over time is when you realize how broken the system is and that you don't actually need to be in danger of getting hit to pull it off.
BOTW's parrying is about as broken and stupidly OP as every other parry system I've ever seen. All you need is simple timing. Again, a
very basic skill you learn very early on. You might be a little thrown off at first by how much warning the enemies give you before attacking, but once you realize how generous it is, it's easy to pull off. There's no reason something this simple should be so rewarding.
Aside from parrying guardians, there's no reason to learn this stuff either. The most successful method in getting anything done in BOTW is weapon spam. In addition, it's almost always the fastest way of getting anything done too. Flurrying is much better than parrying and you'll end up doing it just by dodging attacks, which you would do anyway.
And to clarify my point on OoT, I'm not saying that it's combat is complex or challenging. It's not. It's a nice system, but it's a simple one they developed 20 years ago when they were still building the basics of a combat system...BOTW just managed to make it even simpler. Not only by removing any need to find openings on your own, but also reducing the amount of different attacks you could make and removing damage multipliers from others.
