sho config vs sho run

Correct. Show conf is the saved config. Show running is the current config that is not saved.

Not until you do the 'wr mem' or 'copy running-config startup-config'

Could someone enlighten me as to the difference?

SHOW CONFIG is the old one before I made the changes, but SHOW RUN gives the one I newly configured

Is my running config saved?

To be precise, from the "sh ?": configuration Contents of Non-Volatile memory running-config Current operating configuration startup-config Contents of startup configuration

So, a show startup-config and show configuration is identical. and unless you have done a "copy running-configuration startup-configuration" or a "write memory" you can not be sure your configuration is saved.
