From what I have read "nuck I head"'s problem is not that they make a lot of money, more that their reality of moving to a new city is not "hard" by most common people's standards.
Yes, they have to become adults and buy and cook their own food and pay rent and all those other things a responsible adult has to do. But, they have zero worries about income and where the money for those things will come from and they do have the support network of team mates and staff on the team for when they might need advice or how to go about handling their new responsibilities.
So yes, moving to a new city as a young man is a difficult thing to do but for a professional hockey player (signed to an NHL club too no less), it is significantly less difficult than another 18-19 year old person looking for a job likely on or near minimum wage.
