Unless the champion has high base stats or a defensive steroid, they won't win because even if they have enough armor to tank the hits, they wont have to damage to kill the other champion in time, not to mention that other champion probably has spellvamp or lifesteal so in the end they will win.
Very few match ups like that are winnable unless of course you counter picked the other person, but that doesn't happen very often in blind pick.
BTW Im talking about right off the bat, not someone that lane swaps 10 mins in. Prospectors blade will do just fine even if the other person has a giants belt and cloth armor.
