Yep, I spent many years at a large, public US mobile game company and it was the same. We had a considerable number of players who had total spend in the 5-figure range, and a few into the 6's. And that's on one single game.
The constant rationalization around the office was basically something like: "They're paying for fun, it would otherwise be drinks/movies/real gambling/etc, we're just a different medium". This, of course, completely ignored the boatload of psychological exploitation tricks that we used to keep people playing (and paying). The game mechanics were literally a rigged slot machine. The meta-game was designed to constantly tantalize you with something just out of reach. The monetization was high-pressure, time-sensitive, and used false discounts to increase value ("Get this $20.00 pack for $1.99! Only for the next 60 minutes!")
It got very draining after a while, and I'm much happier now that I've left the industry.
