It doesn't, but at a sentencing hearing convicted people are allowed to make the court aware of any circumstances which would result in the sentence causing unavoidable harm or hardship to people who have committed no offences. In some particular circumstances it might result in a judge giving a non-custodial sentence when a custodial one might otherwise have been on the cards. It can also result in someone keeping their licence after getting to 12 points where, for example, their ability to drive is essential for the well-being of a seriously disabled child.
As for the rest, it's just the normal information that the defendant's barrister passes to the judge to inform the sentencing decision.
As you can see, in this case the judge clearly felt that the offences too serious for any consequences and expressed remorse to avoid a custodial sentence, which is as it should be of course.
