Is there a threshold to becoming a trader?

I've been reading the European Union (Consumer Information, Cancellation and other rights) Regulations 2013 and I'm confused about the term trader, its defined in the Regulation as:

"“trader” means— (a) a natural person, or (b) a legal person, whether— (i) privately owned, (ii) publicly owned, or (iii) partly privately owned and partly publicly owned,

who is acting for purposes related to the person’s trade, business, craft or profession, and includes any person acting in the name, or on behalf, of the trader."

But then every definition I get of what a person's trade is is even more complicated.

So my question is is there a threshold at which an online seller becomes a trader for the purposes of the Regulation or are all online sellers automatically sellers or does it depend on frequency or profit making? Like if I sell some things on adverts or let my flat on airbnb for a few nights am I a trader or would that only come into play if I was doing it very regularly? Is it a case of "I know it when I see it" rather than any hard or fast rule?
