Exactly true.

> One reason has been that drag in the disk produced by surrounding gas makes the grains move inward toward the star – which can in turn deplete the disk rapidly in a process known as “radial drift.”

I’ve been working on this, have a sizeable computer program that calculates it, as well as out of place recycling of components by throwing them out vertically.

> caused by a young planet carving its way through the disc. As the planet moves around in its orbit, its motion creates areas of high pressure on either side of its path, similar to how a ship creates bow waves as it cuts through water. These areas of high pressure could become protective barriers around sites of planet formation; dust particles are trapped within them for millions of years, allowing them the time and space to clump together and grow.

OK. It’s possible. Usually though, planets have the exact opposite effect. Note that this is different to Saturn’s rings, because what we’re talking about here is clouds of hydrogen gas, which are missing from Saturn’e rings.
