Now, it doesn’t (in general) mean “Is likely to receive, if convicted”, which some people tend to assume, but it also doesn’t mean nothing. And given the fact that upward departure is allowed from the federal sentencing guidelines, but not from the statutory maximums for the offenses charged, it is literally all you can tell with certainty from the charges themselves.
In this case, probably not - 20 years is pretty stiff, and the crime implies that typical sentences are much less than that.
But if the maximum sentence was say... 6 months instead; or just a fine. Yeah - I think that would be useful information.
