Here's the announcement from Adobe as to limits on number of assets under review:

I suppose you are submitting Generative AI assets. Have you ever had any accepted? Are you following all the guidelines for correct category, title and keywords ? If not, you should delete all the submissions that are non compliant, because they will be rejected.
Submitting more assets isn't going to get them reviewed any faster, because Adobe still primarily reviews the oldest ones first.
