And I'll give you another piece of advice for your "very good in mathematics and in observation". It might take you to the next level.

"And we assume that Number of Buyers are the same than registered ** Users, which should be pretty close to work with. That means that 1541 Users spent almost 1.2 Millions Dollars.Which seems not realistic to me."

What's not realistic is assuming the number of buyers is the same as the registered ** users. So you already made a mistake at the base of your calculations, so of course whatever you produce from there is not realistic. Rubbish data in = Rubbish data out.

Official Fortnite ** has 495,000 members. So is that all the players of Fortnite? Or is it 350 million?

It's like saying there are 20 users who post about AB1 on Hot Copper. So is the total number of shareholders of AB1 20?
