It only allows them to be blocked with static rulesets. And these rulesets have a maximum size of 50. There's no way this is large enough to cover all your websites. It's also trivial for an anti-adblock script to try a few different urls until it finds one that isn't in your static ruleset

The maximum number of rule sets is 50, not rules, as your own link clearly and unambiguously states.

The actual minimum (not maximum) number of supported rules is 30,000:

In reality, Chrome supports over 10x that. And UBOL doesn't even use/need the minimum, sticking to around 17,000.

So that's plenty to cover all your websites. Which is why UBOL works perfectly fine in practice.
