The MS in Business Analytics is a newest specialized masters being rolled out by many schools. These specialized degrees are great, but they are also revenue generating programs for schools, many of which have seen declines in their traditional MBA programs.
GMAT scores are important as area your other metrics that indicate success in a program that is heavily quantitatively focused. Since these programs are newer than MBA or other specialize masters the admissions criteria are a little more flexible. I wouldn't worry yourself on specific metrics as it is very hard to find applicants for all of these specialized programs right now. You have a good US job market, difficulty in getting sponsorship for international students as well as COVID limiting travel so less international applicants. All of which makes things easier for those who do apply.
Hope this helps.
