Public vs. Private Forms
When the form is public, the person that receives a link to it can immediately view it and edit it.
When the form is private, the person that receives a link to it cannot immediately view it and fill it out. Instead, they are shown a message that prompts them to check their mailbox: an email message is sent to the email address associated with the link. The message is referred to as the "Private Form Access Email".
