My wife is at the stage in her career where this is relevant. When thinking back about the phrasing she uses, when making content for someone else to present she commonly says "I need to finish making these slides". When she is putting together content for her to present herself, she says "I need to finish making this presentation".

All that said to say, I feel like the terms are related, not the same.

Just my two cents.

53 here. Seems like overnight Power Point became "slide deck". I'm just gonna roll with it.

Slide dick

Maybe they meant as opposed to the others who are 80?
