As you correctly point out, those are revenue figures, not profit. $10 billion from Google out of $60 billion in profit is significant. Apple saying they 'care' about privacy while making +15% of its profits from Google alone is hypocritical.
As much as I would like them to default to and support DuckDuckGo instead (hell, it would be a match made in heaven if Apple were to buy DDG and make it their privacy centrepiece), a lot of people would be confused if they got DDG instead of Google, so I don't really think it's fair to make it out as some "chink in the armour". It's a business win-win in my eyes and doesn't affect me at all.

Historically, for example, Playstations were sold at a loss and the games were sold at a profit and a licensing fee to offset that loss.
In the more modern world, Steam and Apple and Epic Games all charge a percentage-based commission for the games and in-app purchases their games have (at least some of them charge the latter). The cost of keeping the game in their catalog is very low compared to the price they charge. The markup is very high; but, it does offset development costs throughout the company. Those development costs may or may not help drive traffic or even use the services that the money-making services boulster, but the money-making services do help pay for it.
If they stop making, marketing, and selling hundreds of millions of iPhones Google would probably stop paying them for default search status.
