I am sure that nearly all users from this forum will be happy to see 200 million FreeBSD users instead of 200 thousand.
It's hard to measure how many people use a desktop operating system. The best way I know of is to look at web browser statistics. To begin with, about 2/3 or 3/4 of all worldwide web traffic originates on mobile (meaning Android or iOS), so desktop use is already a small fraction. Further breaking desktop use down, I found the following statistics: About 76% is Windows, 16% is Mac, 4% is unknown, 2.5% is ChromeOS, 2% is Linux, 0.01% is FreeBSD, all other OSes are smaller. That's not a joke: FreeBSD is 200 times smaller than Linux, which is already only a few percent of total. The total number of clients using web services is several billion (a large fraction of all humans on the planet are still not connected to the web, amazingly enough), so multiplying this out puts the number of FreeBSD desktop users at about 50,000, give or take a factor of 2 or 3.
And personally, having more desktop users on FreeBSD will not make me happy. At best, it is irrelevant to me, as I chose to not use FreeBSD on the desktop, instead I use it for servers. Actually, I think a lot of desktop users is a net negative, since in many cases desktop users tend to be less experienced and less thorough. A lot of traffic I see on this forum or on Reddit about FreeBSD desktop users is just "distro hopping": users who think that FreeBSD is sort of another Linux distro, they want to try it once, it doesn't work the way they expect, the get frustrated or angry, post a few questions, and then give up.
