Is white label a reseller?

Excuse me, I'm a bit confused about something. Could you clarify for me, is a white label essentially a reseller in the world of cryptocurrency and finance? I've heard the term used in different contexts, and I'm wondering if it's a direct analogy to the traditional reseller model where one company buys products or services from another and sells them under their own brand. Is that the case, or is there a more nuanced distinction between the two?
