I saw something on Twitter recently about something like this. Think of the people playing your game in actual physical space. 10 people? You just had a nice party at your house. 30 people? That's a fairly busy cafe! It really helps to contextualize the numbers on the screen.
Also, set your own goals. Don't compare to others. I have two tiny games on my account that have gotten ~20 plays each. I'm super proud of that, but I'm sure if someone was used to getting 1,000 plays they would be devastated to see 20. It's all relative. Just be proud of yourself for what numbers you are pulling and think about how to do better.
