As pointed out by Keshav, you are misinterpreting the meaning. I'd like to add by putting these lines into context. These two lines are the 3rd and 4th lines of the Doha with which the [Hanuman Chalisa] begins. The full doha is -
 Shri Guru Charan Saroja-Raj Nija Manu Mukuru Sudhaari
 Baranau Rahubhara Bimala Jasu Jo Dayaku Phala Chari
 Budhee-Heen Tanu Jaanikay Sumirau Pavana Kumar
 Bala-Budhee Bidya Dehoo Mohee Harahu Kalesa Vikaar
The meaning of these four lines is as follows.
 Using the dust from the Lotus-like feet of the divine Guru, I clean my mirror-like mind,
 And describe the pure glory of Lord Rama of the Raghu dynasty – the allocator of the four types of outcomes – Dharma (Righteousness), Artha(Material wealth), Kama(Pleasure) and Moksha (Freedom from rebirth),
 Recognizing my ignorance, I remember you oh Lord Hanuman – the Son of Pavan (the God of Wind),
 Please bless me with strength, knowledge and wisdom and cure me of any diseases and scars.
What Tulsidas is doing here is saying that he is not knowledgeable enough to pray to Lord Rama who is an incarnation of Lord Vishnu the supreme deity. However, as described in other parts of the Chalisa, Lord Hanuman is most knowledgeable when it comes to serving and praying to Lord Rama. In addition, a prayer to Lord Hanuman is believed to please Lord Rama Himself. In this context, Tulsidas asks Lord Hanuman to bless him with knowledge so his prayers may also reach Lord Rama.
