Hello. I'm sorry that the parts don't fit, according to your ideas, but it's not primarily a problem with the models. It is necessary to realize that each 3D printer has certain printing tolerances and to take them into account. For characters and things that don't have to fit anywhere, these imperfections are normally not a problem, but as for these models and similar ones, if necessary, the models must be scaled - that is, one of the parts must be enlarged or reduced (in this case only in the X and Y axes and of course just a little - most likely it is only a few hundredths, at most tenths of a millimeter difference), which can be done easily in the slicer. I will be happy if you try this and let me know and ideally if you adjust the rating. All the best.
