yes and no.
of course tefila is an avoda shebelev etc. but it is expressed in the words חז”ל were mesaken to say. and just thinking about the idea of tefila without saying the words you are not fulfilling the mitzva of tefila. and whatever Chazal tell us to do is RATSON HASHEM, HASHEM wants us to say these words and to say them correctly. at the same time yes you are right if someone is saying the words and trying to connect to Hashem his tefila is still worth much even if some words were not pronounced correctly according to dikduk, because of his good intentions.
Reb Levi Yitzchak Barditchever was melamed zechus on those who are davening in a way that the noise coming out of their mouths is a noise of mumbling etc. He said that a mother understands what her child wants even when her child is mumbling, so too Hashem understands everyone’s davening. but obviously as i said this is a limud zchus, but one should make an effort to pronounce the words properly.
