Old outdated learning information?

So i am new to unreal engine and want to get into it. However some videos of the learning section, seem to be outdated? Is it still good to use and relevant to learn? or is it not recommended?
Also, what would you guys recommend on the best content or way of learning unreal engine? are they any good courses on like udemy or good YouTube videos that explain unreal engine features in simple plain English? Because i want to use it, to it’s full potential.

Please help out a student :frowning:

Many thanks
