No, they use "high fructose corn syrup", which is, just like table sugar, a mix of fructose and glucose (sucrose is 50% fructose and 50% glucose). The increase in the fructose fraction in HFCS over table sugar is single-digit percentage.
It's not "fructose" vs "sucrose", it's a difference between something that's 50% fructose and 50% glucose (table sugar) and something that is 42% fructose and 53% glucose (corn syrup).
