The belly is the weakest part of many tanks yes, since it's not expected to take much fire than the front, sides and rear, and you're doing something very wrong if you receive a shot from a tank or infantry AT weapon on the belly. Modern vehicles are currently bucking the trend though due to the threat of roadside IED's, resulting in better protected bellies (exemplified in vehicles like the MRAP). For WW2 vehicles though, the belly is still quite thin yes, and would only be thick enough to provide structural support for the tank.
