Not true. A coax cable has inductance but near zero pickup. A twisted pair has inductance but near zero pickup. A woven cable, or other poor designs, will pick up RF and for these cables the amount of pickup may vary with inductance.
To avoid RF pickup what you need to aim for is symmetry and/or screening, not low inductance. Coax works because of the screen provided by the outer, and the fact that the outer and inner are concentric. Twisted pair works because of the frequent polarity reversals. Now it may be possible to design a woven cable which is almost as good as twisted pair, but why not just use twisted pair? Most people use untwisted pair quite successfully for speaker cables, but of course there is only little money to be made from untwisted pair as this is a commodity item.
