Statista estimates that 74 million will be using VR hardware this year, with AR users just short of 10 million worldwide.
I have thoughts to this statistics. It may be real that only 10 million users per 2022 year have turn on their VR Headsets. But the number could be less or higher and I prefer ranges.
According steam stats MAU estimated 1-2 million users per month. Oculus has 2-6 million active users per month.
For doing any output thought we need to understand how MAU works and according this understanding, finally estimated range between 5-15m.
