This video highlights the differences between electron geometry, which is the geometric arrangement of the electron groups around an atom, and molecular geometry, which is a geometric arrangement of the atoms bonded to a central atom.
@VdsLaur you are right. In a bond the electron pair is distributed over two atoms while a lone pair is located on just one- since it's bigger the lone pair forces the other electron pairs together and the angle is less than 120 degrees.
I think there s something wrong with your angles. When there s a lone pair, the angles are smaller because a lone pair takes more place. So it must be < 120 degrees in the first example ( I learned it that way at school)
