amazon reselling

Is it wise to tell people I’m a amazon reseller if people ask about it? I mean I see all these videos on the web and on YouTube of people that are very successfull in the amazon FBA business and wonder what and how they tell people about their business except ofcourse for those who actually create their own products and sell them. I just want ideas on how to respond to people who would ask about my amazon selling business because I do plan on becoming an amazon reseller.
