Yup.
The difference between them is called CC: "Combined Chloramines" or just "Combined Chlorine". This is the stuff that gives bleach and pools that chlorine smell, and irritates eyes and nasal passages. Having zero CC is, indeed, the goal.
My pool can be as high as 8 or 10ppm and STILL not smell like "chlorine" because CC is 0. Stick your arm in and IT will smell like "chlorine" as the FC metabolizes all the "contaminants" on your arm and skin.
