Carbohydrates aren't converted into fat unless they're consumed far above maintenance calories
That said, loading up glycogen stores can make it less likely that dietary fat will be used for energy as glycogen is the priority energy source

To put it simply: carbs and fat can both contribute to a caloric surplus which can result in weight gain either way, but of the two it is the dietary fat that's stored as it requires the least conversion
Processed carbs do still have several characteristics that make them more likely to cause caloric surplus in many cases
They are often found in overly palatable foods that are designed to be addictive, though in some cases (ie donuts) they are also combined with fat

In one of his lectures, Robert Lustig references an interesting study where children are either given soda or water before a meal
The study found that those that pre-loaded with soda consumed more calories from the meal, despite the added calories from the sugar in their drinks

In population data we see similar trends, with soda and fast-food consumption associated with more obesity, but not the consumption of other carbs like fruit, honey, or starches
I think it's clear that the issue is processed foods conducive to excess caloric intake, not carbs
