Why does my Android still say low storage after I transeferred the apps?

AC Question

So recently my samsung tab a just said warning, low storage and yet I havery a 32 gb sd card installed. I went and started transferring apps from internal to the external storage (the SD card) and when I checked my device manager it said I still have 94% of storage space used and only 6% remaining. Why didn't it work? Am I skipping something important? I don't know what to do.
