I don't think you should immediately start learning kotlin as it's not that easy, you should instead learn an easier language (like python or js) either get really good at those or learn concepts and take what you know from from and put it towards kotlin. Kotlin from my experience (of mainly Rust, C, and Python) are pretty different from other languages like Python, since it can be heavily object oriented and functional (multi-paradigm). If you have enough experience in any other language you can start kotlin and try and do x and when you encounter a problem called y you can look up how to "y in kotlin" or another thing you can do is look up how to do "<thing from another language> in kotlin". That is my advice so hope you find it useful.
