Can someone explain or point me to a source where I can find out what the numbers in this area mean?

Its histogram information regarding your ADU.  Your camera converts photons to electrons, and depends on camera sensor and bit depth.   I am certainly no expert, but other sources you can learn about optimal exposure of your flats and light frames.  Getting the histogram (and ave ADU) correct means you don't overexpose your image and blow out your stars.
