Your marks in 12th are not going to help but your marks in JEE Mains only will count. With 200 marks you have a reasonable chance of getting admission.

Hi Priyanshu,
Yes, of course, you can apply abroad. You must meet admission requirements which differ for different universities and programs. International students must take IELTS or TOEFL too. First, you decide what to study and where.

Aayojan School of Architecture would be an option, other than that you can check the Council of Architecture approved colleges in the link - https://www.coa.gov.in/show_img.php?fid=216

Chances are very less according to your wishes. At least class 12 should be qualified with good or decent marks to get admission in a reputed college.
