I’ve been instructed by my therapist on breathing techniques for anxiety reduction. He used “deep breathing” and “belly breathing” as synonyms for diaphragmatic breathing.
I have (and I think my therapist has) also used “deep breathing” to refer to the breathing exercises that use diaphragmatic breathing as a component. I think that’s shorthand/synecdoche.
(Edit) I should add, as well, that slow, large, and diaphragmatic are all three important in those breathing exercises.
