No, if you read that example, there is less than 1 GB which is stale (the diff between the first and the third number):
>> Windows Explorer Reported Size of Component Store : 4.98 GB
>> Actual Size of Component Store : 4.88 GB
>> Shared with Windows : 4.38 GB
As I've said, you intentionally didn't quote your machine's third line but I'm sure it's not a 5 GB difference.
Moreover, that difference can be purged if necessary. Which you can also do on your machine with just a single command, per link on the same page:

There is a trade-off, the probable case why nobody does it unless really necessary:
"All existing service packs and updates cannot be uninstalled after this command is completed"
