I'm selling Lunar on Paddle and the average transaction there is $19.21 (from the $23 baseline price). So they're taking on average 16.47% and that's including VAT, sales tax, credit card royalties and service fee.
On the App Store, even with the Small Business program where the tax is only 15%, I'm losing about 25.63% from the sales each month (still including VAT, currency exchange losses, store fee etc.)
Oh and I also have to pay taxes for this income to my country's government. That's another 10% off the year's income + 15% mandatory health insurance and 15% pension fund.
The money is going towards profits. Apple's App Store profit margin is ~80% and it increases every year[1]:
> Barnes calculated that the App Store had hefty profit margins, which increased to 78% in 2019, up from 75% in 2018, and generated $22 billion in commissions for Apple last year.

Unsurprisingly, the bulk of App Store revenue is from games.
I don't see Nintendo (or Apple) authorizing alternative game stores on their handhelds any time soon.
Apple doesn't make most of their revenue from selling games. It's selling microtransactions in games. They are basically skimming off a few thousand digital casinos at this point.
