Source? https://www.businessofapps.com/data/apple-statistics/#AppleT... says there 31M active Apple TVs in the US. https://9to5mac.com/2020/09/02/apple-tv-market-share-report/ says Apple TV has 2% share of 1.14B global TV platforms. These don't look like 13M/year of sales.
Besides it seems like comparing apples to oranges. Apple TV works with existing TVs which are already billions in numbers. VR devices are completely new devices. Meta has sold 20M headsets SO FAR, not in its lifetime.
