Mobile expanded like crazy these past few years, so yes while you are right that f2p generates somewhere well above %90 of revenue the remainder is still a lot of money, most likely more than the whole paid market was before f2p dominated. For an independent dev trying to "just" make a good living that can be more than enough, even if it's utterly uninteresting to the zyngas and kings do the world.
