I am not so sure. People who play 5e have lots of fun with it. It's already proven to be an amazing edition of D&D.
It's harder to sell people on the game again. 5e reached FAR beyond any TTRPG's reach. People who are playing D&D 5e now might not be as up to date with everything. And if they knew of 5e24? Would they go buy it? I am not so sure. We already know many people are fine with just playing what they are used to.
5e24's biggest competitor isn't Daggerheart or Shadowdark or Draw Steel, it's 5e.
Now the fact that it seems to have been doing well doesn't mean it will ever even out-sell 5e. As we know, 5e kept selling for years and years, and even now it might still sell better than Dragon Delves. The longevity of 5e cannot be underestimated.
Now, I am mostly enjoying 5e24, but anything I wrote here is just based on assumptions. 5e24 might never get the momentum 5e had.
