no, mass murder is not serial killing - by our standards.. we don't class it exactly as legal law does.. for our standards a serial-killer has to exhibit certain traits to separate them from slashers and terrorists etc.

most important rule of serial killers is that they try and hide their crimes, if they just openly kill at random they are unlikely to count because they don't have a survival instinct or don't fear punishment (Joker is an unusual example because it depends on writers if he is one or not, most modern takes of Joker are more mass-murderers than legit serial killers since he doesn't hide what he does from anyone and rarely fears being captured.)
