Note the highlighted word.
Does not mean one does not receive graces at all (and remember one is in a State of Sanctifying Grace).
Certainly we need to repent of such if they happen -even if we have to do so daily as we struggle to turn away from a particular deliberate venial sin and live more free in Christ.
Yes
deliberate venial sin is what in particular we ought to work by grace against (after mortal of course) - and *repent of such quickly and calmly *if it happens (see my post above). It yes such can impede our progress (thankfully though we can quickly repent if we commit such!). The more one cooperates with grace and the more grace perfects one - the more and more of a saint in Christ one becomes - the more and more profoundly united with him.
Knowing too that without a special grace - we cannot avoid ever committing some venial sins - hence they are called “daily” sins. But we can work to avoid “this sin here”. And let us daily repent --calmly turning with trust to the Lord. And frequenting the Sacraments.
It is good to see a longer description of venial sin -pay attention to the whole:
Catechism:
1863 Venial sin weakens charity; it manifests a disordered affection for created goods; it impedes the soul’s progress in the exercise of the virtues and the practice of the moral good; it merits temporal punishment. Deliberate and unrepented venial sin disposes us little by little to commit mortal sin. However venial sin does not break the covenant with God. With God’s grace it is humanly reparable. “Venial sin does not deprive the sinner of sanctifying grace, friendship with God, charity, and consequently eternal happiness.”

Again see my post above about quickly seeking forgiveness (calmly) of venial sins in so many ways. For one remains in a State of Grace and such can be repaired “from within”.
Also read this from Pope Benedict XVI - meditate upon it and the reality of being a Christian in Christ:

(read it to the end - maybe print it out - keep it for meditation).
