Rendered fat calories?

So im mostly eating beef mince thats 17% fat content.

I usually make patties and toss them in the oven. So today i actually poured aside the rendered fat and weighed it. Turned out to 89 grams.

The beef mince pack is 700g and it says 227kcal/100g

And beef tallow is 900 something kcal per 100g. Does this means that if i dont eat the rendered fat aswell im actually only getting a bit more then half of the calories that it says on the mince packaging?
