Does it really means that much? I think that numbers will always favor Apple when there so much choice on the other side, the diversity will make the sales number for a specific product be on the low side compared to a single product (with different variations of it, counted together).

Just like when there are headlines saying "iPhone X beats the [make][model] in sales", if you pool together all Android flagships from different makes that get released that same year then those numbers could vary significantly against Apple.
