Invoke Method - Add / Adding to Dictionary

In the academy example Data Manipulation - Practice 3 - Dictonaries and Integers I do not understand where the integer value 1 is coming from when invoking the “Add” method.

When I remove the “Add winner to the list” activity and re-enter the same acitvity again it does not work anymore and gives this error: Practice3_Dictionaries_CompetitorsSummary.xaml: ‘Dictionary`2’ does not have a public instance method named ‘Add’ matching the parameter types, generic type arguments, and generic type constraints supplied to InvokeMethod ‘Invoke Method’.

How does this Invoke Method “Add” work exactly? I understand it takes the key from “WinnerName”, but where does the integer value 1 come from?

Thanks for any help.
