no
Hi. I’m kind of new to Minecraft updates so I have a question.

The chunks in which you have been (the chunks that you have already loaded) won't change but if you start to explore new places and you are lucky, you'll find monuments that have been included in the new version.
I think.

When you update the game to like 1.20 or whatever, do your worlds update with it, like will my creative world have a completely different terrain and everything or not?
99% of the time, nothing you have already done on your world will change, but all the chunks you havent loaded will be updated
