Not even close.

The law is, if in the last 5 years of ownership, you used the property as primary residence for two years in total, then you are eligible for primary residence gain exemption. 

So， last 5 years of ownership is : 2023/12 - 5 years = 2018/12 

Your time as primary residence is   2019/10 - 2018/12 = 10 month.  

Sorry, not even close. 

2.  If you sold last year  2022/12

last 5 years of ownership would be 2022/12 - 5 years = 2017/12

Your time as primary residence   2019/10 - 2017/12 = 22 month, then it's much closer and I'd suggest claiming the tax exemption.
