I was thinking 10K copies as a metric for even modest "success" for a game, but you're right about the expenses and income... That said, depending on where you live, that's a pretty good income.
In 2021, only the top 8 % of games sold 10k copies or more, so if you were among them, you were quite successful.

In addition, a large fraction of those 8 % were probably games by AAA studios, so your chances as an indie dev are even lower.
