Bizarrely enough, that didn't seem to be a requirement.
But no, it doesn't. It completely ignores the digit, just groups by the string and counts that.
The problem is very weird and stupid though. The input is clearly logically a list of dictionaries with a string as a key and a count as the value. This is K, not Bash, you should be using a list of dictionaries, not a string. If you have that list (let's call is myList), in K you just need to sum the dictionaries together and it will automatically adds all the counts together. So the code would literally just be "+/myList".
