Dried meat is protein-dense: a 1-oz strip pack brings 9 g of protein for 116 calories. On the energy-density scale, 410 kcal per 100 g puts beef jerky at the very high end. Protein density is strong: about 8.1 g of protein per 100 calories.

A typical serving (1 piece, large, 20 g) has about 82 calories, and 100 g has 410 kcal. Calories scale with weight, so double the portion means double the number.
There are 33.2 g of protein in 100 g of beef jerky, which works out to about 6.6 g per serving (1 piece). That is a genuinely high protein share for the calories.
Yes, in the plain arithmetic sense: 25.6 g of fat per 100 g supplies about 56% of the calories. Whether that fits your day depends on your totals, not on the food alone.
