As your screenshot indicates, you have not updated.

Your screenshot tells you that you require a Wi-Fi network connection to download the update. Then it must be installed.

The pop-up tells you exactly why.

The app requires iOS 14 or later.

No, you are not updated. That is showing you that you can download and update the iOS. You need to do that first. You need to connect to wi-fi and then see this, Update your iPhone, iPad, or iPod touch - Apple Support
