Support and ADC can flip one way or the other depending on the situation. I listed it this way because the ADC doesn't usually need the creep gold as much since they're racking up the champion kills. --- There are no stupid questions. Just pointless questions asked in incredibly stupid ways.
Ideally its ADC>mid>jungle=top so your carries are well... carrying.
That said there are far to many variables to even judge that. You can easily get a counter lane going for someone and that person may have to just hide under tower to survive. There are multiple champs that don't tend to win lane but can roam hard ( Twisted fate). Once team fights start you'll see people with AOE start taking a majority of CS.
