That table *seems* to be mostly (if not all) residential and/or small business type devices. I suppose those are more likely to contain default credentials than enterprise type devices such as ASR/ISR routers, Catalyst 3850/9000 series switches, ASA/Firepower, etc.
I have not been able to find a "current" (Post 2018) list of enterprise device default credentials.
