Couldn't have said it better.
Also, if you wanted to set every player to the same gold and lumber, you could do it all by..
-For each integer A from (1) to (12 [or whatever player you want to stop at])
Set (Player (Integer A))'s current gold to (value)
Set (Player (Integer A))'s current lumber to (value)
The "Set Gold/Set Lumber" action is a Player - Set Property
And to set a player to an integer, you have to go to a conversion, convert player to integer.
