During fermentation a lot of the sugar is converted to acid. But there is still more sugar than regular vinegar has. So real aged balsamic vinegar has more calories from the grape sugars.
Vinegar is 5-8% acetic acid in water. The alcohol that forms in the process of making it is negligible. There are traces of alcohol in vinegar but a very small amount. Wine vinegars such as red or white wine and balsamic vinegar do start with a dilute wine which is then fermented. Instead of the bacteria fermenting sugars, as happens when the wine is made, bacteria from the acetobacter family use the alcohol in the fermentation process.
