The American colonies seceded from England, but the elite in the colonies remained elite and the elite in England also remained the elite. Thus it was not a Revolution at all.
Thousands of loyalists would disagree. And even some of those elites who remained would be ruined as time went on.
You are approximately correct with regard to local effect. Although a great many of the colonial elite remained Loyal to the King, and for them presonally it certainly was a revolution.
Our Revolution was, however, most definitely a “revolution” from a world history POV. As can be seen from its defining language, the most revolutionary statement in human history. “We hold these truths to be self-evident, etc.”
From a purely provincial POV our Revolution was more or less a continuation and completion of the Glorious Revolution of 1688, which turned Britain into a constitutional monarchy. Our revolt was a conservative revolution to protect the threatened principles of the 1688 revolution.
“The American ‘Revolution’ wasn’t really a Revolution “
That’s the way the Marxists like to portray it.
But, to the contrary, it was much more a revolution than those that exchange one absolute power elite for another, as did the French and Russian, it put in place a Constitution that based tenure on election, rather than accident of birth, and that was a revolutionary idea in the 18th century.
