$17,000 is probably one semester (1/2 year) of tuition and room and board fees and would be due at the start of the school year. This amount would be consistent with the average price of college in the U.S. The "bank something" probably refers to a letter from from your family's bank which confirms you have the funds needed to support your studies in the U.S. This letter is needed to obtain the U.S. government student visa.
