Its in the Democrats hands. Whatever happens, Trump doesn't care because whatever the outcome is he will win.

If a DACA fix doesnt pass = His base will be happy as well as all the conservative republicans who will back him up (e.g Steven King). Everyone will eventually forget DACA existed, but he will be remembered as the president who stood for "law and order"

If a DACA fix does pass = He will boast about having been able to change the immigration system while increasing border security and limiting immigration. Something no prior president has been able to accomplish, and he will be remembered as the president who legalized some poor kids who needed desperate help (I am sure Fox news will dramatize it better)

That is why Trump is now sitting comfortably in his white house waiting for Pelosi and Schumer to reach out. He will win either way.
