Now my question is....why when I install apps my "RAM" decreases? Or is is "RAM" the one that has the 2 partitions and ROM only gets the OS installation?

RAM is only used for running programs/services... I mentioned this before but you probably missed it.

RAM is basically a place for programs to store information that it needs to access quickly - as RAM is much faster access than a hard drive, NAND, etc. So the OS uses RAM as a buffer so to speak - between the processor & storage device.

So this is a place for the system to store things temporarily - you can't store things directly on RAM, as it would get cleared out on device shutdown/restart.
