There is statistically no difference if one is weighted because it’s gone from 6/36 to 1/6.

Just want to expand on this as it’s the most direct explanation.
With two die there are 6 ways to you can roll a seven (each side has one way to add up to seven), and 36 total combinations (6 sides * 6 sides). So the odds are 6 times out of 36 or 6/36.
With one weighted die, you have a set value (say 3 for example). There is only one side on the other die that will equal 7 (4 in our example). So you have 1 out of 6 possibilities, or 1/6 chance.
However, this is only true for 7. If you were targeting 2 for example, the odds can change substantially. Normally you have one way to get 2 (1 and 1) so you’d have 1 out of 36 possible rolls or 1/36. If the weighted die was weighted to 6 though, you’d never be able to get 2, so your odds would be 0.
