I have to agree $100k/day seems close to unbelievably high, so I had to do some napkin math. In short, it seems it may be possible.
If the avg player dies 10 times, and the ads shown had $.5 CPM, then to make a dollar you'd need only 200 players. So to make $100k/day you'd need 20M daily actives, which is very high but it was really popular around those days.
Is 20M daily actives possible? Yes, because if the average play session is 15 minutes, with that many players you'd have ~200k concurrent players. There's currently a game on Steam called "banana" where you just click on bananas, and that one has 292k concurrents. There are also several Roblox games with that many concurrents, so it checks out.
