When you mentioned the "click" number is bigger than email click numbers, according to my exp. there are 2 possibilities:
1. Is the "page view" in Adobe is included on Visit level? Which means, any landing visit from email campaign and all the sequential clicks. If yes, that's reasonable since all the clicks happened in the visit lead by one email campain will be included.
2. Campaign email was forwarded by recipients to someone else, or artifical traffic (bot traffice)
2.1 check with your email vendor if they are able to provide information about how many times the email is forwarded
2.2 if you are recording email user info (in encrypt), check unique ID or the default Adobe Marketing Unique Visitor ID and IP/Cities info. We used to use a way to find those traffic to identify the bot traffic, e.g. Level 1 suspicious bot traffic: same Visitor ID pageviews from different cities within 1 mins.
in the last, you may need to check the "click" from email is unique click or just clicks.
