It occurs to me there may actually be a way to measure this, if I take the question quite literally. Here's the Google ngram graphs for the words "occult" and "magic"
It looks like there was in fact an inflection point to an upturn in "occult" and "magic" references around the time Advanced D&D was released by TSR (1977-1980 for the core rulebooks). The timing is, if not related, incredibly coincidental. However, I have a few caveats that should be added.
"Personal experience" is anecdotal of course. But I was into D&D at the time myself, had a lot of friends who were as well, and I also knew several Wiccans (and a couple of dabblers). I've met exactly one person who was into both. Otherwise, it was a completely disjoint set.
In general Wiccans didn't think occult forces were something to toy with, and the dabblers were your right-brained dreamer types.
D&D players tended to be left-brained mathy types who didn't believe in much of anything supernatural. That version of the game was heavily math reliant, so if you didn't like spending a lot of type playing with numbers and stats and adding things up, it really wouldn't have appealed to you.
Part of what made the whole BADD thing so annoying for us was that clearly they believed in magic and demons way more than any of us did. If anyone was out there promoting that stuff as real, it was the anti-D&D people.
