Those are games that are talked about so I'm not sure how that confirms anything beyond people are discussing these games.
People are discussing those games, but are discussing them
significantly less than 5e, and people are talking about 1e less and there is no drop in 5e discussion. People are talking about OD&D far more than either 1e or 2e (almost combined).
You might want to try something else if you are trying to prove me wrong.
Well... as mentioned there's the Hot Games chart.
There's also that D&D is still at the top of the Games chart of amazon.com (and .ca), well ahead of Pathfinder. And not just the Core Rulebooks, but also
Curse of Strahd. Unlike the 4e era where Pathfinder and used copies of the 3.5e books were outselling the 4e books.
Curse of Strahd was also hit pretty high on a few book sales charts.
It's been almost two years after release and 5e is still hanging atop the charts. It's sustaining its sales despite the lack of releases and continued competition from other publishers.
It's not just a hit, it's a huge hit.
Keep in mind, at this point during 3e's lifespan, WotC had already announced 3.5. And during 4e, they had announced Essentials.
While a few people in your immediate area might be trying other games (either switching or as a break), this does not seem to reflect larger, world-wide trends where 5e is doing quite well.
