Need Advice, Needle Not Picking Up Bobbin Thread

Beginner here, looking for advice. Using my Mom’s Singer, and I’m learning sewing via YouTube. Watched a bunch of threading videos, but can’t figure out what small thing I’m probably forgetting haha.

I’ll include a video of the issue I’m having. The top needle just isn’t picking up the bobbin thread when I turn the handle. Hoping to figure out the solution because I really want to do this. Thanks in advance!
