DME? Confused

I'm confused here...

My first batch of beer was made using corn sugar as the starter. I was told to use that by the LHBS. I read afterward that it's not the best for taste... So I went to another LHBS and bought was I thought was the replacement, but now I'm not so sure!

I bought a 1Kg bag of Muntons Amber Dry Malt Extract. Is this the replacement "sugar" for fermenting? Or is this what I boil and add hops?

Just a little confused.

DME - dried or LME liquid can be used for priming, creating a starter, or as part of or all of the fermentable bill.

Priming sugar or dextrose can be used for priming, as a small part part of the fermentable bill but should never be used for a starter.
