Not particularly. Read up on it from an unbiased source and you'll notice that most vital humanitarian items (medicines, food, vaccines, etc.) are exempted. While luxury and consumer items are mostly untouched as well. It's actually private personal accounts and industrial transactions of the politically affiliated capital owners, that support the current government, that are sanctioned. Also oil sales specifically. The sanctions were also gradually reduced for almost two years during negotiations, then completely halted after a partial agreement in October last year.

The, "us sanctions are killing Venezuelan people" is actually a global left propaganda piece. The Chavista government was killing Venezuelan people and stealing money way before the US instated sanctions.
