Will Gurobi give sub-optimla solutions even the Gap is very small (<0.01%) for MINLP ?

    The default MIPGap in Gurobi is 0.01%. As soon as this gap is reached the optimization run finishes. That means that two runs that for example differ in some parameter seetings could result in two slightly different objective values. But for both runs the MIP gap is below 0.01%. If you need more precision, you should reduce the MIPGap parameter.
