Does everything - everything in our heart and every external event- happen according to God's plan? (Catholic)

I think everything - everything that takes place in our hearts, and everything that takes place externally - happens so according to God's plan. I don't think my opinion conflicts with our free will. The catechism teaches that God's plan requires cooperation of his free creations, but it also teaches that "all are laid bare before his eyes, even the things that are yet to come to existence through the free action of his creatures". I think that God had incorporated all our free actions and decisions (which we are responsible for) into his plan from the very beginning. Like, even Judas' betrayal was a part of God's plan (he clearly foresaw that Judas will betray Jesus from the beginning; and he permitted it to happen in keeping with his plan. It is Judas own downfall and it was his own decision that he will betray Jesus, but God incorporated this Judas' free will into his plan). If something - however tiny or insignificant it can be - can happen unexpectedly outside of God's plan, how can Church be so sure that our final ultimate end will be achieved? So my question is: Is it correct to say that "everything - everything that takes place in our hearts and mind, and everything that takes place in external world - happens according to God's plan"? Please answer according to Catholicism.
