Calorie supply is irrelevant. The main source of calories today is sugar. People in developed countries like the US get 14% of their daily calorie intake from sugar, some countries like Brazil get over 20% from sugar. That’s way above the recommended 5%.
Another issue with your logic is that land used for grazing can and is simultaneously used for other needs, and it also supports natural bio diversity. Crop land is pretty much a dead land.
The chart also considers protein supply for this reason.
It’s extremely rare that grazing land is used for anything else. In fact, over half of tropical deforestation is done to create pasture land for cattle.
