I have a question someone here might be able to answer.

In my personal stats page, there is an item called "Total payouts". Can anyone tell me what that relates to? In my case it is exactly 30k sats. I can't imagine that the lottery is going to have such a nice rounded number, also I can't recall ever winning with lottery tickets. It also isn't the amount I've won with betting or that I've received as interest. I can't think of anything else...
