It isn’t showing an outflow from the groundwater slice, each circle is an expanded view of the small slice in the circle above. The only thing missing is the percentage of the small slice in the circle where it begins. The soil, atmosphere, and organism water are not falling under groundwater, they are just much smaller slices of the freshwater circle.
If you want to make it much easier to read, separate saltwater and freshwater, and change the bottom charts percentages from 52% and 38% to 0.52% and 0.38%.
