is it worth it for a newbie to start playing Diablo IV now?

I didn’t even know this game was online and I ended up seeing that it’s available for free on Game Pass. I had never tried it before because it’s a pretty expensive game. Anyway. I’ve been watching some videos and it looks interesting. Kind of has a Mu Online vibe, I thought that was cool. But since this is Diablo 4, there have already been other versions. And if I’ve never played any of them, is it still worth starting now or will I not understand anything about the game? Is it worth starting from scratch without knowing anything?
