You're asking about the difference between subnetting and networking concepts. A Class A network with a /8 mask allows for 16,777,214 unique addresses, but only one subnet (the original network). You remember that Class A networks can support 127 distinct networks, which is why you think there are more subnets than shown. The terms "subnet" and "network" are related but distinct—subnetting is a method to divide a larger network into smaller ones, while a network refers to the entire set of addresses. So yes, they're connected but not identical.

Classful addressing has largely faded from practical use, though it remains relevant in theory most of the time. Currently, everything operates without class distinctions, allowing networks to be divided into any number of subnets as long as you adhere to the rules (largest to smallest). In everyday talk, "network" and "subnet" are often used interchangeably. For instance, referring to a "10.0.1.0/24 network" or its subnet is perfectly acceptable.
