That's possible, sure, but the evidence here doesn't support that conclusion any more than it supports the reverse. When you have a small group of things that clearly weren't chosen at random, the safe bet is that they don't imply anything about the set from which they were selected.

Since the major component of Google's profitability is its search business you would have to filter for that. Much of the rest that they do isn't exactly a shiny example for profitability. Also, it's not exactly easy to say who and what exactly contributed to profitability, it is way too complex and environment also plays a role, as well as competitors (if they mess up big time, does that mean you are good?).

Sure, an accountant will be able to give you an answer how one individual human or piece of equipment contributed to the result. It will be a different one depending on what you need the number for though (to calculate taxes? to make an investment decision? to allocate production resources?), and it is quite arbitrary.
