A typical serving (1 large, 4 g) has about 5 calories, and 100 g has 116 kcal. Calories scale with weight, so double the portion means double the number.
There are 0.8 g of protein in 100 g of olives, which works out to about 0 g per serving (1 large). Treat it as an energy source rather than a protein source.
Yes, in the plain arithmetic sense: 10.9 g of fat per 100 g supplies about 85% of the calories. Whether that fits your day depends on your totals, not on the food alone.
