Hmmm. I did some research on a few games and you are surprisingly correct. However, I did notice something else too.
Nintendo doesn't need extra sales numbers from PC. Their games sell record breaking amounts while being exclusive. Of the top 50 best selling games of all time, 7 are Nintendo games that are either Switch exclusives or WiiU ports, where they did much better on the Switch. Sony, in total, has 1, and Microsoft, in total, also has 1 (2 if you count Minecraft, as they bought Mojang during the latter's heyday). Half of that list is Nintendo.
