Questions

Does PRODUCT treat an empty cell as zero?

No. PRODUCT skips empty cells and text in a range, so one empty cell does not turn the result into 0. A cell that holds 0 does.

Is PRODUCT the same as multiplying with *?

For a few cells, =A2*B2*C2 gives the same result. PRODUCT is shorter for long ranges, and it skips text where * returns
