Yes and no. There are different types of efficiency, and volumetric efficiency is simply the volume of gas consumed by the engine compared to its swept volume. That means a 3 litre engine with 100% VE will consume exactly 3 litres of air per cycle (ie two revolutions). Of course forced induction can increase VE way above 100%, but some NA engines can get greater than 100% in certain conditions (usually via careful inlet and exhaust tuning). So if you look at it that way, a turbo engine is more "efficient" than a non-turbo engine. However, if you're talking about thermal efficiency (ie percentage of energy extracted per unit of fuel) or fuel efficiency (distance travelled per unit of fuel), turbo/supercharged engines aren't necessarily any better and often they're worse.
