I don't think anyone doubts that odin is a real programming language that you can make something in. The part that is doubtful is that it enjoys any level of popularity.
Popularity is a bit subjective though as popularity also determines on all the projects built in that said language. Zig got a lot more popular because of the projects that have/had been built on it (Tigerbeetle/Bun) which signaled production-esque use of Zig.
I do understand what you are saying though and I don't think that I have a meaningful thing to add in that and Odin is relatively popular within some circles but the question seems to be if its popular (enough*)
