The DSM is just a compilation of named clusters of ambiguous and arbitrary symptoms that have been agreed upon by some arbitrary board of psychologist and psychiatrists.
It's not like the DSM is some infallible book of mental disorders backed by rigorous mathematical proofs. Rather, the DSM-V seems to be constantly criticized, lacking evidence, culturally biased, etc., and it mainly benefits health insurance companies more than patients and clinicians.
FWIW, the DSM, ICD-11, Neurology, etc. all have differing definitions of the word addiction.
