Yes, they know. It’s right in the OP:

In line with our usual practice, we increased Google’s fine since this is the third time Google breaks the rules of the game. But a mere fine in this case is not enough to deliver real and tangible solutions for the market and to protect our consumers.

This is why we have also ordered Google to stop its illegal practices and to put an end to its inherent conflict of interests in the Adtech industry.

Google has 60 days to inform the Commission on how it plans to do so, and if it fails to propose a viable plan, the Commission will not hesitate to impose an appropriate remedy.

They were not just fined. They were fined and given a warning that, because it was the third time, the next move is to enforce the rules with a court order. Which can include things like preventing them from operating in the EU, seizure of assets, and personal consequences for the decision makers (seizure of assets, criminal charges, etc).
