Does the saying, "Whoever seeks ruqyah from another person deprives himself of being among the seventy thousand who will enter Paradise without reckoning or punishment," apply to one who asks his brother for du'a (supplication)? And does one who is unaware of the defectiveness of seeking du'a in terms of tawhid (monotheism) still have a chance to be among them?

It is legally permissible for a Muslim to ask his Muslim brother for supplication, and many scholars have reached a consensus on this, citing evidence from the Qur'an and Sunnah. However, it is preferable and better for a Muslim not to ask anyone for supplication, but rather to turn directly to Allah; because asking from creation entails humility and out of fear of taking intermediaries. As for the statement that asking others for supplication excludes one from the seventy thousand who will enter Paradise without reckoning, this is an invalid analogy; because it contradicts the explicit texts permitting the asking for supplication, and due to the difference in interpreting the hadith "they do not seek ruqyah."
