Exactly. I mixed soda syrups for my small business and had to learn what actually goes into it all. Soda is generally 80% soda water, and the syrup is usually only 50 °Bx (roughly 50% sugar by mass). Of course with sweetners the syrup is almost entirely water since you need a tiny amount of the sweetner to get the same level of sweetness. In an average soda drink, the flavor and dye is about 0.6% by volume of the syrup (again, more water since it's in solution), and the preservative is 0.2%. The amounts are so tiny you would have to consume a completely unreasonable amount to even get sick, let alone do lasting harm (except for the sugar, obviously).
