You don't have to know it, but it's a good thing to know!
It's actually easier than the other way once you learn how to use it (looking through search results to make sure it's the official link, clicking through installers, having to think about updates, etc. vs. just opening a terminal and typing winget install whatever).
But the terminal intimidates people. So I expect this will mainly be used as an optional "tech tip" sort of thing.
