As you no doubt know, there are 12 possible major chords because there are 12 different piano keys on which you can build those chords. (There can be more than 12 names for those 12 chords, of course, because we can call the same chord two names, such as Db or C# — we’ll do a video on enharmonic chords another time). Once you know those 12 major chords, it’s a snap to learn the minor chords, because all you do is lower the 3rd of the major chord one-half step.
