Do you think people who borrowed someone money and never paid back will get karma?

My aunt owes me money in 2019 I told her about it she just didn't answer me like she ignore me. And then her son owes my sister $100 he never paid her too so I guess he inherit it from mom that they never pay loans. I just noticed no matter how they earn money no matter how big the money is they dont even get rich or still broke even if they have a job. Like I wonder they dont even buy nice things or pay debts.
