Software Engineer with (90+5), getting to (95+5) in January

Hi I’m currently at 90+5 for NSW 190 visa (applied October 21st). In January I will have completed my 1-year experience and will have (95+5) points. What would my chances be of invite before April 1st 2022 when my current visa is set to expire? I’ve also applied for 491 visa as well.

Also, would it be wise to convert to a Student visa around March?
