What they are likely referring to here is strength to weight ratio. By more intelligently distributing material in space, one can get a higher strength to weight ratio than using solid material. Of course geometry does in fact influence material strength. One way geometry can influence material strength is by making crack propagation more difficult. In a simple plane sheet, a small crack at one end can easily propagate to the other end of the sheet resulting in failure. However, if we put a number of holes in our sheet, it becomes more difficult for the crack to propagate. A new crack has to be made each time the crack crosses one of the holes. Now this result of an additively gyroid structure having a high strength is a bit comical. One of the first 3d printing artists produced a sculpture of the gyroid a while back[0] and in fact the files for said sculpture are well known[1] and have been used to test 3d printers. It's sort of funny no one thought to crush one till now!
