Look within the "other" section of the chart and see that just under 200,000 people are using SNES controllers to play games on Steam.Controller compatibility in PC games used to be managed only by the individual game developers, meaning a game supported a predetermined set of hardware and players selected from these prescribed input options. In 2015 we began an experiment to find out what happens when the community is less constrained. We shipped tools that allow Steam users to map controls from various devices (e.g. Steam Controller, PlayStation controllers, Xbox controllers) to any combination of inputs that the title understands (e.g. keyboard keys, mouse movement, controller presses). Additionally, we created a system to share and modify these controller configurations so the best input schemes boil up to the top, allowing the cumulative efforts of the community to benefit us all. These two features, remapping and sharing, served as the foundation of what we now call Steam Input.
Three years later, the Steam Input experiment is starting to bear interesting results. By supporting so many controller types we've learned about which controllers are being used on the platform and by accommodating customization we've learned how players prefer to interact with different genres. Today we'll share figures on which controllers have been connected to Steam, how controllers are being used, and what happens when a new controller is released on the platform. We'll also discuss the Steam Controller and how hardware choices set it apart from other controller types.

I'm assuming this mean genuine SNES pads with a USB adapter, and not just clones which would likely fall under "PC gamepads." I found this number pretty damn impressive.
