It's huge but having worked in the industry, I'm not surprised :-)

The landscape of video games in the past (+/-) 10 years changed quite a bit. Nowadays, it's the biggest type of money making entertainment product (by a magnitude more than movie) and the acquisitions of studios start a multi million figures, up to billions. Seeing suits in gamedev studios now became a common occurrence.

I did the math and came up with that figure and it was so ridiculous that I spent a hot minute trying to figure out how I did the math wrong.

Video games are the #1 entertainment choice for young people (born 1997-2007). TV and Movies are #5 on their list.[1] Avengers Infinity War is the most profitable movie and opened with a box office of $2B. So, $5B/yr for Fortnite doesn't seem wildly out of range to me for an ongoing entertainment property.

What's even more fun is remembering this is a "Free" game
