It varies. Some fighters in the past have had less than 20 amateur fights before going pro n some have had over 100 going pro
that would be something you ask a trainer or professional boxer
If a highschool Basketball player was as good as Kobe, he can or should also turn pro asap.
You can literally have 1 amateur fight and turn pro if you wanted too. Having an amateur background is not a requirement to be pro. And there's not a certain limit of fights you need either to be pro.
There have been world champions who did not have an amateur career, and Olympic champions with over 200 amateur fights.
everyone is different so there is no correct answer.
I would think you would want enough experience so your trainer thinks you can handle the pressure of fighting professional.
I know this is not a straight forward question, but how many fights should an Amateur Boxer have before he/she turns professional?.
