While running Windows, have you ever thought "I wish I could make c:\whatever be on a different drive, because this stupid application/daemon/user is filling all of C"? That's how UNIX filesystems are attached inside each other. Instead of becoming arbitrary drive letters with files inside, they get put where convenient, with one main partition at the root of it all. The file tree is organized like /opt, /usr, and so forth to make it easier to parcel different kinds of data on different partitions.
If all those extra filesystems weren't mounted, they'd just be perfectly ordinary empty folders.

So (in my mind)...any other folders listed are by default in the / file system.
Yes, exactly. Any folders which aren't within any other mountpoints are inside /

virtual-filesystems
virtual-filesystems(7) Miscellaneous Information Manual virtual-filesystems(7)
NAME
virtual-filesystems - event signalling that virtual filesystems have been mounted
SYNOPSIS
virtual-filesystems [ENV]...
DESCRIPTION
The virtual-filesystems event is generated by the mountall(8) daemon after it has mounted all virtual filesystems listed in fstab(5).
mountall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with
other activity.
This event is typically used by services that must be started in order to mount other filesystems. When this event occurs, common filesys-
tems such as /usr may not be mounted. For most normal services the filesystem(7) event is sufficient.
EXAMPLE
A service that wishes to be running once virtual filesystems are mounted might use:
start on virtual-filesystems
