OP's parents do not have the funds in the bank.
Beware of people who will put into your account temporarily to show funding. If the USCIS detects this, they may consider it fraud which is treated very harshly for future visa applications.
There are several options avaiable to you.
First, find a less expensive institution; your choice seems quite inexpensive so this will be difficult.
Second, complete your undergraduate study in your home country and go to the US for graduate study. Depending on the university and program, they may have work-study opportunities that are not available to undergraduates.
Third, complete your undergraduate studies and go to the US on a work (H1B or L1B) visa and take classes part time in the evening.
Fourth, join an "au pair" program which will allow you to work for a family as a child care worker and also take some classes during your off time.
