Key length is likely something perfectly normal, What this article is talking about is entropy, which is a measure of how truly random your RNG is.
https://en.wikipedia.org/wiki/...
Basically everyone uses predictable RNG generators that always output same numbers for a given seed. The security of this depends on providing truly random seed that cannot be predicted. Im guessing hardware wallet has not enough external inputs to generate reliably random data on software level (eg linux uses keyboard, mouse and other devices input as sources, which this device mostly lacks), resulting in something like "this seed is 1000 bits long, but all but 40 of them are 0s"
