No. A riot just a public disturbance involving uncontrollable mobs of people. The Jan 6 mob didn't break into an airport, they broke into the Capitol building overtly seeking to perform acts of violence against the government.

Not all political demonstrations are insurrections, of course. For example, demonstrations for Palestine, or against abortions, or for better worker's rights, or for women's rights — those are not insurrections because they are advocating for a specific cause, not the overthrow of government. If an anti-Israel demonstration turned into an armed mob that entered the White House or the Capitol seeking to bring about their demands with force, then it would be an insurrection.

Intent is important when discussing the meaning of words. Carrying a knife with the intent to chop carrots is not a crime, but carrying one with the intent to chop people is.
