The reason that Docker Desktop on Windows creates a Hyper-V container is that it needs a Linux operating system to allow you to run Linux containers. Because containers aren't VMs, they rely on a host operating system to provide the low level services that they need to function (CPU, memory, I/O, ...). One way to think of it is that you're doing cross-platform development. If you wanted to do Android development you would need to run an Android emulator on your machine to run your applications without deploying them to a phone - this is pretty similar.
This isn't representative of using containers in production. This is just a development setup that you can use while working with containers locally.
