first all, vulgar words are not entertained here
your SS shows you have total of 8GB storage, after adding the rest of the storage sizes, it sums up to approx 8GB [nothing seems wrong with that you'll get similar if you buy an SD card and view the storage on it]
again, you can use a file manager such as xplore to verify [amt of storage displayed in xplore + amt of storage used by system in your SS should be equal to 8GB]
