No, only a licensed user can view content on Tableau Server.
You would have to purchase Explorer or Viewer licenses to allow others to view the content published by the Creator user.
Buy the user based or core based tableau server license and access the server.
Since you only have a creator licence, people only with the login and password of your tableau server account can view the dashboard.
However, you can also download and send workbooks to the respective viewers. Ask you viewers to download Tableau Reader on their device so they can download the workbook you send them and open it.
