There are two types of private colleges in Karnataka. The ones that come under their own university and the ones that come under Rajeev Gandhi University of health sciences. If you want to get in to Deemed colleges then MCC. NIC. IN is the website for you. A very few amount of seats are given under the government quota via the state counselling Kea (not able to give you the link. Do google it) If you would want to join Private colleges coming under the RGUHS, then you should get the admission directly via KEA.

Both are good subjects. Economics will help you pursue a career in financial research, equity research, financial journalism whereas Statistics will give you option of pursuing a career in a range of Data Analytics related field which is in demand now a days. You need to decide on your interest areas, and then based on it choose your specialization.
