Indeed, web 3.0 is the big world. If we go to find and learn every single term of it, this will take much time. Like if we take DEFI only, it is another huge world. As well as dApps, DAO etc. I am sure to say that I don't know all of these deeply. But I know some of these, as cryptocurrency, DEFI, and dApps. Maybe I know more than that, or maybe I should know more.
