Bandwidth = data per unit of time. So for the same amount of data, faster bandwidth absolutely decreases load time.

If a website requires multiple round trips to complete a given request, then latency will also matter, and sets an absolute minimum floor to time-to-display (TTD) regardless of bandwidth. The higher your latency, the slower that process. In theory it's possible for an SPA (single-page application) to be more responsive despite an overall larger page weight as it can incrementally request and present additional content. In practice such pages often perform worse on time to display due to both increased total data transfer and round-trip request requirements. A lightweight HTTP/2 HTML+CSS only site can be far more performant if it's based on static pages and request/load dynamics.
