How do you burn 650 calories in an hour?

While browsing through friends’ articles, I found a @run.kirsty.run talking about running about ten kilometers, which helped him burn 650 calories. I don’t know if the information is true or false, because I am not a specialist in the field, but the information helped me even if the number was not accurate. So I wanted to post it, because I always walk, but I don't know if calories are burned in the same amount? Or is it different from one sport to another, and I wonder what is the sport thanks to which we can burn fat quickly and in a large amount? , Greetings to all of you.
