> There's difference between running on a margin of 5% and 90% at those scale
OP said revenue, not profit. And neither of those numbers are relevant to Google, which runs a 32% (28%) operating (net) margin [1].
That said, yes, Google is the most profitable company in the world [2]. But its $116bn is not in a different league from Microsoft's $102bn, Apple's $99bn or Saudi Aramco's $96bn.
The value of revenue as a metric is that you can't really play financial games to screw with revenue, while there's lots of stuff you can do to inflate or deflate your profit. See, e.g., Hollywood accounting.
Neither revenue nor profit is the full story, though.
