What were/are the major differences between a King, a Sultan, and a Khan?

Good day Historians!

Is it possibly just semantics?

I also have this (possible mis)conception that Kingdom bears the same idea as a Sultanate and a Khanate, where

King - Kingdom Khan - Khanate Sultan - Sultanate

Thanks!

Apologies for the Kingdom, Khanate and Sultanate looking like a mess. I couldn't space them properly on mobile. Thanks!
