Could this be possible? Burning 1000 calories from just 🚶‍♀️

I’m a university student so I walk around pretty much all day. I noticed my Apple Watch recording my steps and the calories I burned from just walking here. They seem insanely high…but could this in any way be accurate?

For reference, I’m a woman in my 20s, 5’8” and 120 lbs. I average around 19k-23k steps every day from just walking around campus + I also play tennis and run at least 4-5 times a week.
