I'm not sure this follows from the evidence in the poll. The poll is designed to skew conservative ("top 3 playable species"), and within that, only three species cross the 25%-of-those-sampled threshold.
It would be nice to disambiguate those who chose half-elf; was that conceptually separate from elf, or do people choose one or the other (which I suspect happens with orc and half-orc)?
So yes, there are clear leaders, but the long tail shows there is an appetite for less mainstream species. I am surprised at how well Tiefling does in the poll, esp. since (IMO) they were implemented so poorly in 5e (and worse in 2024). But again, are people choosing aasimar and Tiefling, or choosing between them? It may be that "planetouched" (or whatever) would hit 25%.
How are Tieflings worse in 2024 vs 14?
They had bad stat combo in 2014 phb.
