Does this "lock" include a chamber that you bring boats into, close a gate

both ends

Yes

then raise or lower the water level in some way so that you are
either higher or lower than when you entered the chamber?

There is a difference in water level (that's what causes the tidal
current flow), but it is fairly minimal compared to most locks found
at river dams.

If my memory is correct they equalize water levels by cracking open
the lock gates, ie, no sluice way or valves, but I'm not sure of that.
