Is (Python for beginners , Python - Intermediate and Python - Core) learnt here enough to know about full Python ?

Answer 1

There is nobody on this planet who knows Python completely because of its thousands of packages and modules. The sololearn courses are just a good first step into the world of Python programming. Even for creating GUIs you have to consult external resources.

Answer 2

No . you will just learn basics from these courses.
For deep learning enroll other courses (youtube,google etc)
