Confiscation of funds gifted to a prosecutor

I read that the court upheld the decision to confiscate over 1.6 million hryvnias from a former prosecutor, even though her mother gifted her this money to buy an apartment. The question arises: why can funds gifted by relatives be deemed unsubstantiated assets, and is there a risk that any large gifts from relatives could also be confiscated? Does this apply only to officials, or can similar situations occur with ordinary people as well?
