Blogger stats include all visitors, while Adsense stats do not.
If you were using blogger before you were using adsense, then of course there would be a difference, depending on which stats you are looking at. Are you looking at the all time stats on blogger.
The difference between 608 pageviews and 48 pageviews isn’t that big. Not only that - many repeat visitors may not count in adsense, such as those repeatedly coming from facebook.
