Are you trying to create a new table (all new data) or a new view (the same data, arranged or filtered differently)?
If you are referring to “Grid Views”, then yes: unless you apply a filter to one or both the views, they will show you the same data. Two (or more) views for the same table are pulling from the same records. However, your records aren’t duplicated. A record in a table only has one instance, the purpose of views is to hide or show records (or fields) without deleting the record from the table.
