Morphology
The components ('no' + 'skin' + 'off' + 'my' + 'back') evoke bodily-harm imagery that can hint at 'not being harmed or affected', so a learner might partially infer the sense. However, the conversational meaning 'it doesn't concern me / I don't care' is idiomatic and not fully predictable from the literal parts, and similar imagery is not universally used across languages, making it only partially transparent.
Etymology
The idiom no skin off my back comes from a simple image: imagine someone taking skin from your back, and if there is 'no skin' to take you do not lose anything or feel hurt. So, it means 'not affected' or 'I don't care'.
