Serious question about getting caught

I live in the Chicagoland area and I was brought over as a minor from Mexico. Currently have a bachelor’s degree with no criminal record or debt and make an honest living and paid taxes for the last 5 years as a contractor. My question is this I currently have the updated licenses from Illinois that say “federal limits apply” and I know that trump will start his mass deportation in Chicago. How does one get caught though? Theoretically assuming that I don’t break any laws. Like how does ICE operate to individuals that aren’t speeding or violating laws, like how do those people get caught. Keep in mind Illinois is a sanctuary state and opposes traffic stops. I also do not look Hispanic nor do I live in a Hispanic area. And I don’t have an accent. For the last 60 years of my workplace apparently there has never been a ICE raid either. So I’m wondering how concerned and scared should I be?
