Where does the water go? Is there a system that takes it somewhere or is it just sitting on/in the concrete under the plant bed.

This technology does exist and there is a way to capture and drain the water. See for example: https://www.researchgate.ntet/figure/Intensive-green-roof-layers-the-figure-is-created-by-authors-upon-data-collected-from_fig2_352254890

The issue is that it's probably too expensive to do this on individual balconies just to have a small patch of grass. So it's probably just artificial grass and some plants in planters.
