More to the point, what do you know about machine learning? How do you think you could learn more?
I nearly know nothing yet. All I have done is I spent few hours and learned some basic concepts like data mining, supervised learning, linear regression, gradient descent. That's it. Even that was at concept and math level. I was able to understand it sine my math is ok. Other than that I don't know anything.

If you define a numeric value in your database as NUMERIC(6,2), then it should always be accurate to 2 decimal places. If you do database calculations on the database server, the standard math rules about precision apply.
However, if you pull values and compute them in a Java application you may have a problem, since there is no "normal" datatype for decimal values except for floating-point, and so if you pull your JDBC/ORM values as float or double, you'll get the standard floating-point fuzz. To get around that, you'd have to either scale the numbers or use a decimal-friendly class like BigDecimal. Which, alas, doesn't have operators, so it's cumbersome to work with.

There was an issue opened almost 4 years ago regarding streaming result support in Postman (specifically SSE) - looks like it still has not been addressed.
