Although Trump has said that he would deport criminals first, these people would be easier. And Trump is all about easy:
“Former President Donald Trump has made the deportation of millions of undocumented immigrants the centerpiece of his dark domestic agenda. And even Dreamers -- as immigrants without papers raised in America, including DACA recipients, are known -- are not insulated from Trump's cruel designs.”

I suspect Trump will go for easy wins. He will frame them as criminals.
I do not see him caring about whether they have a criminal record. There are no mitigating circumstances.
He tried to expel them once. And it was a different court then.
He will be successful this time.
