yes it is cc0 but mentions are always appreciated 🙃
In this case you should add the license into metadata for the asset packs:
"Edit asset pack->Metadata->Release Info->License for assets" It will increase the size of audience that will be able to find your art
P.S I also recommend to add explicit CC0 mention in the description
ok thanks 😊
