Hi and welcome to the forum! And, welcome to the wonderful journey that is Revit! The best approach for your learning depends on how you best learn to do things. I, for instance, can't stand to watch YouTube videos but many will recommend them. Early on I learned by reading books and applying what I read into modeling in Revit. I also had the opportunity to have a great mentor/teacher that I did online training with. There's Lynda.com which I believe is a subscription service. Another issue for you is, are you learning Revit of the fun of it or are you doing it as a part of an employment requirement? If per employment maybe your employer will pay for classes or even personal Revit training. There's lots of ways to learn and you should get lots of advice on the subject here

Check with your local community college. They may have a professional development department that teaches the software.

And check with your local / state library. Mine has free access to lynda.com.

you guys still have libraries? How '80s is that

Boise's mayor wants to hire a fancy out of state architect to design a 70 million dollar library. Sure would be nice if the city would spend the $600K design fee locally

welcome alto.
great books like mastering revit, revit no experience necessary and other are all available, i normally use book depository. Ian ant bimscape has heaps of free beginner tutorials as well as some on of his on YouTube. Heaps of Youtube users have channels, like the main Autodesk one and some of the guys from here. Just subscribe to their channels, instead of doing silly searches for revit on youtube and copping poor practice from some. Find the quality, its important. And yes, Lynda.com is a beauty. Autodesk have a large collection of information on their site. Follow the tutorials to understand the tools, not to just get the building built. And then there is the obvious, practice, practice and more practice. Big learning curve. Certainly a program that delivers the goods if you use best practice. If you don't embrace the parametrics of it all, you're missing 90%. Example is labels vs text. And this forum no doubt has saved the bacon of many. Terrific resource. Lost count of the number of times I have been puzzling over something and then my daily check here comes up with the answer.
have fun
