When you create/edit Gravity Forms plugin forms on your WordPress website, a "Newsletters" field is available under "Advanced Fields" to add a subscribe checkbox to your form.
You can configure this "Newsletters" field by specifying a custom caption, auto checking it, adding a custom checkbox label, choosing the list(s) that users will be subscribed to and also map Gravity Forms fields to custom fields in the WordPress Newsletter plugin.
As users fill in your Gravity Forms plugin form and the subscribe checkbox is checked, their email address and other chosen fields are subscribed as you configured it.
