This is correct.

"Hey are you working on that deck?"

"Yeah, I just need to run to Home Depot and get some more nails"

A deck is that wooden structure on the back of your house. A power point presentation is an electronic file made up of "slides". There is also a "deck of cards", but no one calls a deck of cards just a "deck". Maybe if they called it a "deck of slides", or you know just use a term that makes sense, like "presentation".
