Why is Ag considered as a transition element, even though it has completely filled d-orbitols in its ground state?

Ag has an electron configuration with 9 electrons in the valence shell and 2 electons in s shell but due to the stability of compeletly filled d orbitals one electron jumps from s orbital to d orbitals and then the configuration of Ag become 4d¹⁰ 5s¹

The properties of Ag lies between that of s- block and p-block hence it is considered in transition series.
