Thanks for the kind words :)
To answer your question, there is information that is shared between other parties but only between the participants in that single transaction. The other participants that were involved somewhere in the chain who contain data related to previously mentioned transaction will have their data updated accordingly if needed.
Therefore, in my opinion, this is a distributed ledger. As I mentioned in the post, the difference between Corda and other platforms / Blockchains is that data is shared privately between the participants in a transaction rather than globally broadcasted to the whole network.
Hopefully that answers your question.
Additionaly, if you wish to delve deeper into Corda I recommend looking at the key concept videos. They personally helped me out a lot when I was getting started with Corda.
