I install apps all the time without seeing an ad, because 90% of the apps I use are installed from F-Droid.

The apps I install from F-Droid often help me block ads in my browser, so I see very few ads as I use my phone day to day.

Meanwhile, my understanding is that Apple's App Store has ads in it, but that's the only app store allowed. So it seems like maybe iOS is the one that "has ads in the operating system".
