If you consider time zones (not every PC gamer is online at the same time), the fact that it's not the weekend, and other factors, I'd estimate the PC gaming audience is at least 100M.
Unfortunately, there's no possible way to get an exact number. There are multiple gaming PC manufacturers, not to mention how many gaming PCs are going to be built by hand. I'm part of a PC gaming community, and nearly 90% of us have a PC built by either themselves or a friend/family. https://pdxlan.net/lan-stats/
