There is unlikely to be a random distribution of "pilots". Those involved will understand what is going on. The system has probably adapted so that what is really happening is continued flying lessons during scheduled passenger services.
Outside aviation it is accepted that 25% of job applicant CV's contain outright fabrications. The world still adapts somehow. I certainly come across people who don't know the basics of subjects they have postgraduate qualifications in. In the good times they can lie their way up the ladder. In the bad times, well... they were the cause of the bad times.
