The residue was just some form of paint/primer/mud/texture from when the building was first built as a few people here mentioned.
fyi @Jim K. and the white thing in my hand was just a paper towel as I was trying to rub some of it off to see if it came off easily or not.

Thanks again everyone for the responses!

Thanks for the replies. Glad to hear it isn't totally out of the ordinary. 

First time wanting to rip up some carpets and did a test in a closet corner. Has anyone experienced white residue under the carpet pad? It took some scrapping to even see if there was wood underneath.

Thanks in advance & hope everyone is having a good holiday weekend!
