the issue that youre having is the fact that many of the objects have different poitns of origin. if you play around with the scale in some of the starter content youll see that some of them scale from the bottom, and others scale from the middle. I honestly dont think there is a simple solution to youre issue, but you can try selecting everything the pressing ctrl G to group them all together, then scaling them down. I think that will make them all scale uniformly but ive only used groups with moving objects so im really not sure.
