Hunting small game is reasonably reliable. Hunting primarily big game, as the study is suggests, is the textbook example of unreliable high risk, high reward strategies we teach undergrads about.

What modern human foragers often do is exploit a huge variety of strategies all at once. They're also highly opportunistic and social mechanisms are used to distribute the successes across a large number of people. For instance, if a bunch of Hadza hunters come across a beehive full of honey, they'll stop hunting and eat it. Such finds end up being a significant source of calories for the Hadza, but the study's argument is that this sort of omnivorousness is a recent innovation.
