Morphology
The meaning 'what someone really feels or believes' is a direct compositional combination of 'deep' (intensely, at a great depth) and 'down' (inward/at a lower/inner level), yielding 'deeply inside'. This adverbial inwardness is cross-linguistically common (e.g., Spanish 'en el fondo', French 'au fond') and follows productive English patterns, so a B1 learner who knows both constituents would likely infer the meaning.
Etymology
Deep down comes from the idea that something is deep and far down inside you, like a feeling at the bottom of a well or inside your chest. So deep down means 'what someone really feels or believes' even if they don't show it.
