Is run differential reliable to determine if a team is good or not?

There are a few outliers this season. Phillies with a negative 17 run differential and yet 52-43 record. Guardians are another example of a negative run differential yet a 49-46 record. Tigers have a plus 30 run differential yet a bad record. Rangers with negative 10 and a positive record.

Does that mean those teams are getting lucky?
