I'm at 478 with my IELTS expiring in July 2023, and I'll be 30 in March 2023.
Unless I'm able to get a job offer or learn French, I don't see a way out anytime soon.
Based on the current trend, the number of new profiles that are added to 500+ CRS are significantly higher. If IRCC continues with the draws every two weeks without a break, there might be a chance for 470s.
Keep in mind that by the end of the year, more people would have earned their Canadian degree, so there's a higher % of people adding to 490+.
I would suggest trying every possible to increase your score, at least the options in your control.
