Does the comma in my example sentence add clarity, or should I leave it out?

I quickly realized, homeless people listen to and trust other homeless
people.

I chose to include the comma to ensure readers understand it was the ‘listen to’ and ‘trust’ that I realized and not only the homeless people. If I don’t use the comma, I’m concerned some readers will misinterpret the sentence to mean, "I quickly realized there are homeless people who listen to and trust other homeless people."

I cannot find any information that will answer my question.
