Fundamentally, yes, except the Steele memo also alleged that there were/are financial elements of leverage. EDIT: The book that this Guardian article is written about does touch on some of the financial ties between Trump & Russia, sorry. Which would surprise almost no one, but we've always thought of it as an explicitly understood two-way arrangement. It may have been that Trump only found out that he was 90% (or whatever) owned by Putin/Russia in Helsinki, or on a Very Special Oval Office Phone Call in early 2017. But I doubt the Trumps were totally in the dark on the financial side of things.

Sadly, the public perception of the Steele Dossier is pretty binary, it's either "hurr durr pee tape" or "hoax witch hunt hit job". There was undoubtedly some mis/disinformation fed to Steele that got sprinkled in, which made it easier to discredit the whole of the dossier, but anyone still screaming "no collusion!" never deserved a microphone. Who fucking cares if there's a pee tape? The slew of Trump's dictator coddlings and attempts to become one himself isn't bad enough?

Can a nationalist fascist be too stupid to know they're a foreign asset? Well, now we know the answer is almost definitely "hell yes".
