No. 50lb/hr AT 20psi. (not "and" but "at). THERE IS A HUGE DIFFERENCE. One is two arbitrary points, the other is a single point on a pump curve.

When you go to buy a pump a lot of marketing will also "misspeak" as most electric pumps will hit 20psi and 50gph, and fewer will hit 50gph at 20psi. To be honest though you can probably do it with a pump out of a newer full size car or truck. You'd be surprised at what those pumps can deliver when they're not running at 45psi. Sometimes if you do enough research and ask the right people you can get pump curves for stock pumps, sometimes its a $15 risk when you walk out of the junk yard with one.

Do any newer cars have external inline pumps? I would like to do this instead of having to get a universal intank setup.
