It is not the only determining factor and a person with high CGPA has better chances of getting into in good colleges or company is not very true and is situation specific, I would elaborate this with some examples. As far as placements are concerned you need to score above a particular range (ex. 8 CPI and above for some companies) to appear for the process. As far as getting in a college for higher studies is concerned, it all depends on university and your overall profile. Again, for example if you have done some phenomenal research and published lots of material, you have given some TED talk and you are applying to IVY league University where you want to extend this research definitely, they are not going to underestimate you just because you have low CGPA. But definitely in certain scenarios it is high CGPA which at least gives you an opportunity in campus placements. Again, for example Mercedes Benz usually short lists top 5 students from each college (based on CGPA or aggregate %) and invites them for the recruitment process in their campus. Thus, if you don't stand in those top 5 no matter how much practical experience you have got, you can't even attend the interview process.
