There are multiple examples of Olympians within GB that are professional - doctors , nurses , lawyers , fireman , policeman , military - they get a level of funding to pay for travel , accommodation, clothing
Are they “professional sportsmen” or professional doctors , nurses etc
Not everyone fits inside a “dictionary definition”
There are people with cycling , swimming etc where someone is “paid” by GB cycling or GB swimming and have no other job and are professional sportsmen/women etc
If someone who only plays golf to earn money then he is a professional golfer
I think its perfectly possible to be both (just like many 000's who hold down more than one job) I can be a professional mechanic and a professional bar tender
Athletes (& tour golfers) aren't excluded from taking another job on top of the sport they get money for (some may need to, some may want to)
