I'm not sure how accurate StatCounter is, given that most Linux users use adblockers. However, according to it, Linux has almost a 14% desktop share in India.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I would assume that “market share” is related to the relative number of units sold/number of active subscriptions/fraction of total sales in terms in revenue, or some similar metric. I run a variety of different distributions on servers (bare metal, VMs and containers) and desktop computers. Do they all count equally? Without giving it more thought, I wouldn’t even know how to determine the market share of Ubuntu in my own home in a sensible way.
With Windows, I can just count the number of active licenses. Oh wait, its zero.
