Hi Aria! Thanks for posting on the community.

As a user on a Team/Enterprise account all your documents are technically owned by the Account Owner. What that means is that the Account Owner can at any point choose to delete a user or revoke their license at which point they could reassign all the documents to themselves or someone else on the team. 

Otherwise all documents in your account will not be seen on others on the team unless you keep them in a shared folder or explicitly share them with others on the team.

Hope this helps!
