I have a 200 amp service ( residential) going to a 125 amp sub panel. That subpanel feeds another 125amp panel am I already maxed out?

If his wire and circuit breakers are sized correctly, who cares if he's tripping breakers upstream? Code, no. Safe, yes. Practical, no.

Same aspect as the dummy that insisted smoke alarms need to be on afci circuits because its part of the bedroom wall/ceiling circuit. Seriously, who plugs and unplugs a smoke alarm 10x a day?

We need more information to know if it's "maxed out". There's nothing in the NEC to prevent you from running a 200A feeder off of a 200A panel. You should check what max allowed branch breaker is per the panel specs.
