About Quality of Service (QoS) settings

Please tell me about the configuration below.
When you do not specify the match condition in class-map,
as there is no such communication exists, if this class is specified in policy-map, is it OK to recognize that it doesn't work (in this case, 10% bandwidth)?

=======================

class-map match-any non-client-nrt-class

policy-map port_child_policy
class non-client-nrt-class
bandwidth remaining ratio 10

=======================

I am unsure I understand the intent of your question.

In general, CBWFQ classes do not actually reserve unused policy class bandwidth regardless of why it is not being used.

The overall behavior should be the same for a class that cannot match any traffic or a class that can match traffic but there is none, at that moment, to match.
