No, or at least no in the sense that if the Jedi in question is a fully trained Knight and knows what he is doing. Against a padawan though?...Ya I could see the win for the Mando there why not? But that doesn't mean he wouldn't have trouble, a padawan is still a Jedi who is trained since a toddler in using The Force and being in CQC.
However against a fully trained Jedi Knight/Master that actually knows what they are doing in combat? No, I mean that was sort of proven with Luke and Obi-Wan against Jango/Boba.
I don't think boba or Jango are full flesh Mandolorian, they are just bounty hunters nothing special. Mandolorians are like a different species then humans they are just a humanoid form.
