Until you leave your house and use your mobile phone as a mobile phone, and then all access is granted to the data-sucking fiends.
And I say this as someone who runs Pi-Hole. But I feel like it is a battle I am using.
That's why I said "or better yet NextDNS", which is not tied to your home.
Apple has the security advantage though if you disregard the information apps leak but then again on both OS's you can use Pi-Hole, or better yet NextDNS, to shut up some of the chatter.
