Can't remove those apps, all bloatware, but they were always there and there was space before, no matter what I do the storage remains full. I've seen this happen often before with other Samsung devices, seems a factory reset is the only solution.
clean Youtube data,and cache,disable google play apps that doesnt needed,disable galaxy store or another apps that didnt used,clean data and cache on Gallery
and dont forget delete the "Android" folder and the other folder that doesnt contain important files,but make sure theres no important data inside "Android Folder",Android data itself could takes many Gigs sometimes
if theres Social Apps like Telegram,Whatsapp or whatever,try to move the folder itself that contain media data to SD Card.
