Essentially, yes. Furries who are AB, tend to have baby furry personas, known as "babyfurs". Furries who are DL, tend to just have regular adult personas, who are also DLs, if that makes sense. Often people have a fursona (their furry persona) at two diffirent ages so they can enjoy being a babyfur, while not excluding themselves from the regular adult furry community.
Personally, as a DL, I'm not particularily interested in babyfurs, although I do watch some babyfur artists on FurAffinity.net. I haven't ever brought my furry self with my DL self in that way, but I probably will someday. For now I kind of keep them seperate, although I do like the artwork of others and such. You don't need to bring the two together if you don't want. Anything else?
Happy to help.
