does unity post games on the app store?

because that is where my main market is

No, you have to do it yourself by getting a developer account.

If you have the Unity iOS add-on, you can publish a game that can then be uploaded to the App Store separately. You don’t require an add-on to publish to the Mac App Store.

However, Unity Union is a method that can assist you in publication of your game to new platforms. See Made With Unity | Unity for information.

(You DO require an additional license from Apple to submit an app to both the Mac and iOS app stores. This is not included in a Unity iOS License.)
