We call program algorithms "language" because we humans understand them, not because they are understood by the subject. The same is true with DNA; the codons do not convey abstract symbology, they only regulate molecular interactions via physical processes.
Then is language the sole domain of humans?
I don't think so. It seems to me that other species have their own languages, which are understood to convey meanings known to them. Dolphins, for instance, seem to have a language.
The key to focus on is not whether a human being can understand the message, but rather whether a conscious agent can.
Language is inherently abstract. Abstraction requires higher-order powers of thinking. Molecules lack that capacity, and are unable to abstract the message. Without a listener, what are words?
