I haven't been to Venezuela, so I couldn't tell you specifically about Venezuela. While there has been a lot of poverty the last couple of decades in Venezuela, there used to be a ton of prosperity. It wouldn't surprise me if there were still a good number of wealthy people with fancy fishing boats in Venezuela despite there being so much poverty.
And while I haven't been to Venezuela, I have been to a number of pretty poor Caribbean countries. I still find some pretty decked out fishing boats, often for hire/rent to international tourists. Or they just are owned by foreigners/tourists. Or as mentioned, they're some of the wealthy people in the otherwise poor country. Rich people are pretty much all over the place, especially in otherwise desirable places to live (some extremely beautiful beaches and coastlines).
