You said iOS in the previous comment and OSX in this one, the chart has an entry for Mac OS and no seperate one for OSX, so assuming iOS is the one you're basing the claim on. While macOS + iOS > Windows, Android outnumbers macOS, so claiming the combined macOS + iOS share means that mac is more popular than Windows is like me using that Android market share to claim that desktop Linux is more popular than MacOS.
