Only a certified tour guide has shown to the authorities that they learned the Czech history, Prague sites and history of art. So such a person is a professional and has the guide licence to prove it... No, the Free tours and foreigners are not professionals, 99% of them has no certification. A licenced tour guide is a professional that you pay for their knowledge and expertise - like when you need an electrician or even a surgeon. You want a professional with all the certification and diplomas, not a random stranger who works for tips only.
