Hi, I have got 98.015 percentile...is it really a good score for a good college? And what least rank can I expect?

Estimating total no. of students who appeared in January Main,2019 exam as 965000, according to my calculations your rank is approximately 19155.You can also check your estimated rank in the article link given below:-

Well this a good percentile but might differ a bit after the final NTA result,i.e.after April,2019.Because NTA announces the final result taking the best of two,so percentile tends to vary depending on the number of students appearing in April,2019.Hopefully you will get a good college with this present rank.

Let's hope for the best.  For any more queries comment below.

According to my calculations your rank is approximately 19155, estimating total number of students appeared in exam was 965000.

It's a pretty good rank to get you into a good college but nothing can be told for sure now as this isn't the final result.The final result by NTA will change depending upon the number of students appearing for the test in April and how the students score.
