If you think that increases in Mac sales mean that macOS is a growing part of Apple's revenue: it isn't: macOS is dwarfed by other products more every year.

According to https://www.apple.com/newsroom/2021/04/apple-reports-second-..., Apple “posted a March quarter record revenue of $89.6 billion, up 54 percent year over year …”.
Mac, on the other hand, grew by 69 percent year over year.
You're speaking about raw numbers.
From that report:
$47.94 billion: iPhone (Up 65%) $9.1 billion: Mac (Up 70% YOY) $7.81 billion: iPad (up 79% YOY)
To let us know what Apple prioritises, though, we need to look at percentages of the operating unit as a percent of Apple revenue.
Mac revenue was 4.8 in 2014, 5.2% in the most recent figure I could find.

We can also look at company reorgs like getting rid of the macOS team, advertisements steering customers away from macOS, and other public facts.
