By “depth” I’m assuming that they are talking about “seeing into” the paint layers when layers of translucent glazes are used in oil painting. Oil paint also becomes more transparent when it ages which also increases that effect in old paintings.
Glazing can also be used in acrylic painting, but it’s much more difficult to get an even, streak free layer because acrylic dries so fast. However, I think it’s possible to get a similar effect of depth.
The majority of painters today don’t use the glazing technique and use paint opaquely, so their paintings don’t have that effect of depth no matter what they use.
