Agreed -- I believe the confusion comes from this sentence in the document:

"Moreover, if the defendant fully complies with the understandings specified in this Agreement, the defendant will not be further prosecuted criminally by this Office for any crimes, except for criminal tax violations, related to her participation in [the FTX scandal]."

IIUC, by "further" they mean "in addition to the 7 counts she pled guilty to [and could serve jailtime for]."
