Chance of Invite for BA 224711 in 2021 under 189/190, 90 points with 189

Currently reside in NSW. I’m still waiting for my 1-year working experience to do the assessment with Vetassess. But my 485 visa is gonna expire in October this year. Not sure the chance of getting invited if I stay onshore. The trend in NSW 190 seems to invite mostly IT and engineering-related applicants in recent rounds. Please advise. Thanks!
