As of Pi-hole V5, the file /etc/pihole/adlists.list is no longer used. As discussed in the V5 release notes, adlists, domain blocks (regex, whitelist, blacklist), group assignments and gravity are in a single database in file /etc/pihole/gravity.db
If you want to add the lists you show in your post, select the lot of them (without the commented lines), copy to your clipboard. Then go to web admin GUI > Group Management > adlists and paste the lot into the entry window, and select "add". Then rebuild gravity using either the tools menu on the admin GUI or pihole -g from the command line.
