Here's the problem with this
You're just a dumb kid who googled "rpg market share" and pasted the first result in here. I, on the other hand, have been monitoring the industry for nearly a decade now.
First of all, ENWorld, faggots that they are, decided to publish numbers from ICv2 - more or less a non-source.
Secondly, there's been around a dozen D&D 5E-centric tabletop Kickstarters that collected upwards of 1 million USD each, which equals about a quarter of your "total RPG market share" figure, which as you can see is complete bullshit.
Lastly, as Lord Bertrand Russell said, "never let yourself be diverted by what you wish to believe". Know more of facts before you spout your nonsense.
