The first "ground" level you refer to is THE ground level, where the airline check-in desks are. From here, passengers take two flights (stopping halfway at the 2nd level) of escalators up to the 3rd (the other "ground" level you mention), which contains the pre-departure security check and boarding gates.
how can an escalator go from a ground level to another ground level (The gates)?
