Unity Pro vs Android/IOS Pro

Hello Unity Developers!

I just got the Unity Pro License as a raffle prize and Im curious to know something. I am aware that Unity allows developers to port to mobile devices without the need to purchase both Android and iOS Pro licenses, but Im curious to know what the differences between Android/iOS Pro licenses and Unity Pro licenses.

Lastly, since I have Unity Pro, would there be a need to get the Android/iOS Licenses in case that I want to make games for Android/iOS or no?

Any input is gladly appreciated.
