First some notation:  You are not creating a class, but rather in 
instance of a class.  The  code
   class Athlete:
     ...
  created the class, and now you are ready to create (many?) instances 
of that class.

A call like
     Athlete(...)
will create an instance of that class with whatever parameters you 
supply.  What you do with that instance after it is created is your 
choice.  Assignment is one possibility, but many other operation are 
also possible:

     x = Athlete(...)
     print( Athlete(...) )
     Athlete(...)+Athlete(...) # If addition made any sense and was 
implemented in the class
     return Athlete(...)
     ...
