8/6/7 Profile, Beginning CAT prep now. Can i get into a good college?

I am an engineering grad (computer). I graduated in 2023, I don’t have a corporate experience but I did start a laundry business, it’s been up for more than a year now and it is profitable. I am a forex trader as well ( A profitable one) so never felt the need to get a job. I am also learning japanese language now, I have my exam in December. For the last 3 years after my graduation I did some freelancing work as well in various domains. 10th percentage is 84%,12th is 64% and graduation CGPA currently is 7.8. I am a little worried about my profile for a good B school, I want to know realistically what are the odds of me getting into a good college, if I do manage to get 98-99 percentile?

I am confident that I will get a really good percentile, the only thing that has been bugging me for so long is my profile.
