The only built-in method for displaying entry data on a page is by using a text confirmation.
If you’re looking for a way to display entry data on a thank you or confirmation page to make it more personalized, you will need to use an add-on like Post Content Merge Tags from Gravity Wiz or a non-Gravity Forms plugin like URL Params.
If you want to allow the user to review and edit their entries you can use GravityView to create a custom view that will show the logged-in user their own submissions.
