The thyroid nodule is a common thing that can be seen in a thyroid gland, and your doesn't have any particularly concerning features, so they call it "indeterminate". It should be followed with repeat ultrasound imaging.
The irregular vascularity is a bit concerning for a lymph node, and that, along with the larger size of the lymph node, may prompt your doctor to want to get further testing, perhaps a biopsy of that lymph node.
Or at the very least, get a followup ultrasound in a few weeks to look for changes.
There's no way to know right now if this is a possible issue with lymphoma or not.
You would need to get further testing.
But the ultrasound results that you post here is a bit concerning.
Best of luck.
Hopefully it turns out to be nothing at all.
