Sugar is 50:50 fructose:sugar and "high"-fructose sugar is 55:45. The slight difference in fructose:sugar between the two is not significant in terms of health outcomes, unless you mean sugar in general.
I can't make sense of your comment, but whatever you're trying to get at is wrong: Table sugar is sucrose. Corn syrup is mostly glucose and contains no fructose. HFCS is commonly produced at 42% and 55% fructose formulations. I don't think HFCS is meaningfully more or less harmful than any other sugar, but chemically there's a significant difference.
