Thanks for the reply HCP! That answered my question very well.

@Abdussamad
I completely understand (and I made sure I understood that before I went to Bitcoin) that and  I've done all my transactions with the wallet. Yet as TryNinja said, it seems one generates more private addresses than used because the total is bigger than the keys funded. I know this because when ask electrum for the value of the funded keys (i.e. sweeping) it generates fewer keys than my total but the value is equivalent to what I have in all my private keys. 

But what happened to the coins that were in the private keys that were not 'funded'? Because the transactions record that coins went to that private address.
Or were they just amalgamated at some point in the course of transactions? I just want to make sure I didn't lose coins somewhere.

When I run the command with CLI: electrum listaddresses --funded | electrum getprivatekeys - it returns 75 keys.
However when I run it like this: electrum listaddresses| electrum getprivatekeys - it lists all of my 100 keys. Same as what it shows in the GUI version.
Why is this? What does funded mean? I believe all of my keys should be funded since I've received them and transactions are OK.
