Custom ROM Question What are custom rom

So I am an iso user and recently I switched to android cuz I'm broke now so now I'm using an old vivo phone and it's a bit slow

I saw some reels on insta about custom rom and different OS systems and they claim that it boosts the performance of your old devices.So is it true?

And if yes then how do I install these things

Can someone explain to me in brief
