No, they are not forgiven when one goes to Mass, per se.I have an interesting twist to venial sins. Venial sins are forgiven when one goes to Mass. Do they still need to be confessed? I usually do because I want the counsel.
They are remitted by a worthy reception of Communion, as well as a sincere general Confession of sins to God (such as the general Confession made in Mass), and even by Holy Water insofar as it excites contrition in your heart, so they are probably remitted when you go to Mass, but not because you go to Mass necessarily
They are under no obligation to be Confessedd, period, even if they aren’t remitted otherwise. However, at least with habitual sins it is a good practice to confess them, even if in generality.
