(1) "no match with me" should be "no match for me".
(2) "dumb" is an adjective. The second sentence should be "you poor dumb person!", but "you" can be ommitted, so "poor dumb person" is acceptable. "Poor dumb" is grammatically incorrect.
Too much phrases;
as always=Anyway; Poor dumb !
=as usually happens
=as usual
=or is expected !
Hence:-As always, you are no match with me.
