Different kinds of sugar are all sugar when they get to your gut.
Nope fruits are high in fructose while sucrose, aka table sugar, is 50:50 glucose and fructose. Fruit has the same or even worse makeup sugar-wise as HFCS, glucose can be used pretty much directly by the body while fructose needs to be processed by the liver, into fat. Evolutionary speaking that makes a lot of sense as when there’s a lot of fruit around it’s summer and you need to fatten up.
Real fruit vs. juice is a matter of fibre and satisfaction from chewing, it’s way easier to overdrink than to overeat fruit.
