Are fluid ounces the same as ounces?

No. Fluid ounces measure volume, ounces measure weight. One US fluid ounce of water weighs about 1.04 oz, but other ingredients differ.

Is weight the same as mass?

Strictly, kilograms and pounds measure mass. In everyday use “weight” means the same thing, and scales are calibrated for Earth's gravity.
