Question – Hello I have a question about the lottery visa and

Hello, I have a question about the lottery visa and the tourist visa for USA. A friend of mine obtained her tourist visa a few months before she applied for lottery visa. Now, she wants to travel for 2 weeks in USA to visit. Will she have problems or be denied entrance in USA based on that lottery visa she made? Are these 2 – tourist visa and lottery visa – conflicting? Thank you very much
