In the picture below, my mac is shared by 5 volumes. Why is this the case? Along with that, why do I have a "Container disk1" and two volumes under that("Macintosh HD" and ""Macintosh HD - Data").
Also, when I try to partition my mac, it won't let me add another volume, stating that the minimum size must be 195 GB. Why does this happen?
A little bit Catalina and a lot APFS.
APFS has Containers that contain Volumes. Containers are like partitions.
Volumes are virtual divisions of a Container, but all of the Volumes in a container share the same total storage space.
Catalina separates the OS from your Data and third-party stuff. The Macintosh HD volume is the OS and is mounted Read Only so nothing can modify it.
Macintosh HD - Data contains everything else and is mounted read/write.
The three other volumes in Container disk1 are:
Preboot - for booting up
VM - Virtual Memory
Recovery - What used to be the Recovery partition. It's now in a Volume under APFS.

I am only asking because I am hoping to upgrade my storage using a solid state drive of 1 TB. I was wondering which format I should make it after installing that drive into my mac. Would it be APFS or Macos Journaled?
For Catalina, you need APFS. You'll need to select GUID partition Map before you can select APFS.
