Technically true, although the industry trend to classify this type of 48V technology as so called "Mild Hybrid" (MHEV), is at least in part a marketing-driven movement.

After all, even 12V vehicles (including BMW's) employ start/stop and coast (sailing). Yet, we don't call these hybrids. It's true that the 48V system certainly makes these functions more robust and also adds regenerative braking, and in some manufacturers' (though not yet BMW's) implementations, electric supercharging. Furthermore, some more advanced 48V implementations are built into the engine/transmission, such as the one used by Mercedes, which allows for all auxiliary systems to be electric and completely eliminates belts from the engine.

So, yes, the industry is moving toward more robust electric systems in all combustion vehicles, and these contribute small gains in fuel economy. But to classify them as hybrids is a reach, and this is underscored by the fact that, when tabulating HEV sales, they are not included.
