This cannot be known until it is litigated. Fair Use is not something you can unilaterally declare and have it be so, just like you can't be like Michael Scott in the Office shouting "I declare bankruptcy!" OpenAI is currently defending itself against the New York Times for this very reason.
There's a multi-factor test that courts weigh the facts against in making a determination as to whether a prima facie copyright violation would be protected under a Fair Use defense:
Factor 1: The Purpose and Character of the Use
Factor 2: The Nature of the Copyrighted Work
Factor 3: The Amount or Substantiality of the Portion Used
Factor 4: The Effect of the Use on the Potential Market for or Value of the Work
See https://copyright.columbia.edu/basics/fair-use.html for a pretty good overview of what the analysis entails.
