Grass, and trees, are not marginally better than concrete, they significantly better.
Trees indeed are much better, which is why I didn't include them in that statement. The carefully manicured grass of a golf course is pretty useless, ecologically speaking. It's too short to be useful for wildlife, being so short means there isn't an atmospherically significant amount of photosynthesis happening, and being so short means the root structure is too shallow to offer the water retention and erosion prevention that proper plant coverage provides. About the only things it actually does a good job of are looking green and being softer to walk on. Concrete is obviously worse in all of those regards, being utterly useless (ecologically speaking) instead of just mostly, but the ecological benefit of a manicured lawn is basically negligible.
