Is elevated pth but normal calcium most likely a parathyroid tumor?

In brief: That's 1 possibility

Besides a parathyroid tumor, it could also be due to low vitamin d levels, or kidney failure.

Low intake or excessive loss of calcium and/or magnesium can also raise PTH

In brief: No, something else.

A parathyroid tumor (adenoma) would have elevated PTH with an elevated calcium level (known as primary hyperparathyroidism).
When the PTH level is high but the calcium level is normal, it is referred to as secondary hyperparathyroidism. Causes for secondary include kidney disease, vitamin d deficiency, and a few other much rarer conditions. It can also occur naturally in some african americans.

In brief: Depends on calcium

If the calcium is elevated or high normal and PTH is significantly elevated, primary hyperparathyroidism is most likely cause and would most likely be treated with surgery.
If the calcium is low the most likely cause is vitamin d deficiency.

In brief: Not necessarily

Your doctor will likely investigate your vitamin d levels relative to pth, calcium, magnesium, and phosphorus.
Elevations in PTH could be the result of vitamin d deficiency also, as well as other things. You may need to see an endocrinologist or possibly even a nephrologist. Please discuss this with your primary care provider to plan a course of action.
