Affiliate and Reseller

Hi I'm new here and I'm also a new YouTuber, I have been looking into the affiliate opportunity for my website and I have also been looking at the reselling opportunity for my website. I'm trying to find out if it's possible to become an affiliate and a reseller? And if it's possible is it viable? I.e. is one opportunity better than the other or doesn't it matter? Similarly, if you have to make a choice between the affiliate program and resell, which would you pick over the other? If anyone has experience of doing either or both your replies are most welcome. Thank you!
