Sorry, that is simply not true. Obamacare was passed without a single amendment (or even a full debate), and without a single Republican vote.
But my statement about the supermajority is true. The Democrats (with Independents) had at most 60 members of the Senate (2009-2010), Republicans had from 39-42 (vacancies and other things going on).
Democrats did not have sufficient control of the Senate to guarantee they could get whatever they wanted.
I recall one of the Republicans predicting that at some future time the Democrats were going to regret having used the nuclear option. That time is probably about right now.
I'm afraid there's no way to put that big cloud back into that shiny metal ball.
