Both a lot of information, and not a lot of information travels through those cables.
It’s going to depend a lot on where you live.
If you’re in North America, the vast majority of the services and websites you access will be hosted on the continent and will continue working just fine. Webpages for European companies may become inaccessible.
If you’re in Australia, some local stuff will continue working, but a lot more things will die.
Services like Netflix almost always have local servers, it’s not financially reasonable to push that much video between continents on a per user basis. They just use those links to sync their various servers as new content is released.
Most phone calls to foreign countries will fail. Almost all of it passes through the internet cables these days, rather than using dedicated phone lines undersea.
The largest providers use CDNs to serve content, which are designed to be redundant and resilient. Cloudflare alone has 335 datacenters on all inhabited continents. Services that don’t need to talk to a single centralised server would be fine.
You are forgetting that those data centres talk to each other using those cables in order to actually have a local copy that they send to the end user.
This caching behaviour will cease to exist if there is no internet connection between the centres.
