No, you’re just refusing to understand what he meant, just to be “right”. You cannot fully block an app’s internet access. You can disable its cellular data permission, and you can disable background refresh, but as long as you’re connected to Wi-Fi the app can use the internet. You would have to manually disconnect from Wi-Fi every time you wanted to use the app. And yes, I own an iPhone.
