It will definitely depend on the ISP, but generally for repeated “AUP” violations they will suspend your service entirely.
Interestingly it’s often not technically the data usage that triggers this, its how much utilisation (generally peak utilisation) you cause and high data usage is a by product of that. Bandwidth from an ISP’s core network to their various POIs that customer connections come from is generally quite expensive, and residential broadband connections are fairly low margin. So lets say they’ve got 100Gbps to your POI that could realistically service many thousands of people, a single connection worth €/$10-15 a month occupying 10% of that is cause for concern.
With my IISP, the base package comes with 4 TB of bandwidth and I pay and extra $20 a month for “unlimited”.
I am not sure of “unlimited” has a limit. It may. It is not in the small print though. I may just be rate limited ( 3 Gpbs ).
