“The relation between different classes (represented by a connecting line), makes up a class diagram.”
Taken from class diagrams. Not everything you need to know it seems. It misses multiplicity at least. (Didn’t read/scan more)
Also, did you really intend to have one-to-many for both client and account? Since you labeled owns. One client multiple accounts is ok for the sample. One account can have multiple owners (clients) in theory but for the introduction (audience is I guess the inexperienced) I would go with 1.
