More often than not, it's difficult to visualise the gap in sensor measurements purely by seeing technical specs. The graphic here may provide you a better sense of the sensor measurements in the ZS25 and A7R III.

As you can tell, both of these cameras posses different megapixels and different sensor measurements. The ZS25 with its smaller sensor will make shooting shallow depth of field more difficult and the Sony A7R III will show greater detail using its extra 26 Megapixels. Greater resolution can also help you crop images somewhat more aggressively. The older ZS25 will be disadvantaged with regard to sensor tech.
