With levels you are adjusting your blacks, mids and highlights. Same as just about every corrector in the world.
Although the UI might look different, you can do the same thing in several ways in resolve. (depending on the type of curve you are looking for between the sections)
Use your color wheels, or your curves, or a combination of the two.
try the curves with all channels locked, and then try with a “Y” only adjustment, you will see a different result.
Switch your scopes to histogram, and you will even get a similar looking display.
