I sold another 3 copies of my book

I wrote a novel and self-published it earlier this year,
and I sell about 3 to 10 copies every month.
The number of copies sold comes to me via KakaoTalk every month like this,
and I just got a message saying 3 copies were sold in August.
I thought it was completely buried since only 1 copy sold in July,
but I'm shocked that people found my book and bought 3 more copies somewhere ㄷㄷ
I've sold about 80 copies in total so far,
does this count as being an author? lol
