Dropshipping Noob Help

Hey, I'm thinking about getting into drop shipping and I'm looking for some tips and I have a few question

1. What is copyright with dropshipping like? I want to make a fornite related store and advertise it on fortnite related Instagrams. Will I get copyrighted?

2. What happens when you get site visits but no sales?

3. Any extra tips? I'm planning on fortnite or phone case related dropshipping and I'll be using Instagram and Twitter to advertise

Thanks
