OP - you have no pending “visa” or any other pending application as a matter of fact. Even your mom has no pending “visa application”. What your mom has is a pending petition filed on her behalf by her sister.
You may apply for a F1 visa, or any other NIV you wish to apply for. Your application will be reviewed on its own merit and adjudicated accordingly. Your own totality of circumstances will be used in making a determination as to your eligibility for an approval or otherwise.
As a matter of fact, there are known folks with approved I-130 who successfully obtained NIVs while waiting for their priority dates to become current. So yes, it is still possible to obtain a NIV with a pending or approved I-130 if the applicant is able to convince the CO of their current ties to their home country and their plans to return at the end of their authorized stay in the US.
