DRY is about knowledge management. The intention is to not avoid duplication of code which is a knowledge representation of the same thing. It does not mean every coincidentally similar looking code must be made into a function, as it would result in a premature abstraction, etcetera etcetera. It's why "minimum three duplication" principle is effective, because it filters which duplication represents the same knowledge and which does not.
KISS is (ironically) a more complex topic. C2 wiki talks about this in an interesting way. https://wiki.c2.com/?KeepItSimple
My more nuanced take I guess is "don't duplicate logic, except if it may in fact be mutable data". It does take some forward thinking to think that this e.g. list of 10 rules should be unrolled and not compressed by meaningless helpers, etc
KISS and DRY are different paradigms, i.e. come from different schools of programming.
Most people would not recognize simple code if it hit them I'm the mouth.
KIES (keep it easy, stupid) is what they mean, and that means following idioms, frameworks, that are familiar.
