I think I found the answer. When I checked Starlink’s site, those prices plans match up with the personal plans, but it appears that the user in the screenshot has a business plan.
Screenshots should be the Business Local Priority & Global Priority pricing respectively. My prices might be different than the original screenshot (I’m in Canada and I’m not sure how they localize pricing), but the data amounts seems to line up with the selections in the screenshot.
I did some digging and think I found the answer (more details in my comment here). The pricing in the screenshot is for business customers, not residential users.
