This is of course a very short message, and almost certainly "broken" in some sense, e.g. perhaps part of it is missing or the operator mistakenly changed something part way through. It was sent towards the end of the war, the U-boat which sent it is being chased at the time and will be sunk before Germany surrenders a few days later.
Dice-rolling seems unlikely as humans think repetitions like "KKZZ" or "VVBB" seen in this message are "wrong" and "don't look random enough" which is why you can't let humans do this work. Also the radio operators probably have better things to do than risk getting executed for wasting resources on such games at a point where Germany has definitely lost the war.
On the other hand, screw-ups due to being stressed by people trying to kill you in a war you're probably aware you've lost already are very likely. I'd be a complete wreck if I was that operator.
