Well, Blender 2.50 up to 2.79 UI was heavily inconsistent and counter intuitive. Everything was done in its own way, even when the same thing already existed elsewhere, hundrets of double entries, cluttered menus, the hotkey dilemma, and so on. And so the slightest change made it even more confusing.
This will change with 2.80. Still quite a few old problems around, but things are a bit more obvious and accessible now. But 2.80 it is still in heavy development, it is in Beta at the moment. And so things still changes. There are also new changes coming for 2.81, 2.82 and so on. And for 2.80 there aren’t this much tutorials around yet since it is still in development, and not officially out yet. It will come.
But there will never be a solution to the dilemma of the thousands of different Blender tutorials for pre 2.79. They are all made with different versions, from 2.50 up to 2.79, with all its small and bigger changes at the UI. What you could do is to grab the Blender version with which the tutorial was made. The old versions are still available at blender.org. Then learn the steps, and then transfer the knowledge to the newest version.
