but anonymous users are still unable to see the Webform submit form. how can I enable them to see and submit the form?
You understood wrongly, the image you posted is for webform submission results, meaning permission to access the results of the webform after submitted.

You need to give permission in the webform itself, simply go to that webform and then click the form setting tab and then give permission for anonymous user.
