Practicing photography on a smartphone is terrible compared to a dedicated device; in both ergonomics (hard to get a good grip, unprecise shutter actuation due to the touchscreen, and sometime unreliable software) and quality (granted, I like to actually print my picture instead of looking at them on a tiny screen; but still the difference is noticeable).
But that doesn't doesn't necessarily mean you need a camera system that cost as much as a small car; you can get plenty joy with an entry-level mirrorless (which would be in the pareto 20% price range).
