Storage space usage is a strange thing. I have a 256GB Xs Max and 256GB iPP 12.9 (2018) The phone is the primary photo/video taker and music player, yet it has 230GB available. Whereas the iPad has 182GB available. Also I'm very surprised about the iPhone's 230GB available number, as the previous 256GB X had less than 100GB available. I set up the new phone from a backup of that phone.
