Cuba had the advantage of being run by an ML party and having consistent trading partners via the USSR et al for decades, focusing on building up industry. They are still very poor due to the sanctions, but do far better than their neighbors (like Haiti) because they can prioritize healthcare, food, community well-being, etc.
Venezuela was never socialist, just had a SocDem party in power that tried to nationalize the oil industry, and were basically SOL when the sanctions regime hit. Chavez was actually trying to diversify, especially food production, but they had maybe 1 or 2 years to do so, tops.
