Yes what you recited it is counted and inshallah you will be rewarded for the recitation specially it is recommended to complete minimum one quran in this holy month
As per the Narration if one recites the one aayah he will
Get the sawab of the recitation of one quran don’t miss the sawab of the recitation
Now understanding yes it is not only emphasised by ulama but it fad been asked by quran and Ahlul bait as to reflect on the quran and understand the quran.if you understand the quran you will get sawab of reading and understanding both.
May Allah increase your Taufeeqat
