Answer:
Yes, of course I agree with this statement.
Explanation:
Material things, like Olympic medals, are nice to have, but if you take a look around and see people suffering in poverty, or because they don't have the means to treat their illnesses/mental disorders, you won't feel as happy about your own possessions. This is why every person, regardless of whether they are famous or not, should try their best to help other people out as much as they can. In Michael Phelps's example, he is an amazing swimmer, but he also understands that he cannot be fully happy with his Olympic glory if he doesn't spread awareness about something that's very dear to his heart, which is the importance of mental health (if you recall, Phelps has a history with depression).
