Can other accounts on a ps4 use the games purchased on an account that is only set as a secondary ps4?

I gave a friend the credentials for my second account on which I bought all the games online. The account is set with him as "secondary ps4" and has no PS plus. Can he use the games bought on this account on other accounts even though my second account is only set as "secondary ps4"?

It does not matter how the PS4 is set or whether it's your first, second, third, or five-hundredths account.

The games bought in the store can only be played under the account under which you bought them.
