Is Regional DNS "Propagation" Relative To Viewing Website

Just want to make sure I understand . . .

If we updated our webhost/domain DNS settings with the Cloudflare DNS settings - and the DNS is/are still “propagating” around the globe (after 36+ hours) - does this mean that if the DNS hasn’t yet propagated within the geographic region in which a particular viewer resides, that the website will not yet display?

In other words … I live in Las Vegas, NV (Western Regional, USA). The closest “server location” appears to be San Jose, CA (USA). If that server does not yhet show as “propagated” with the new DNS info, does this mean I will not be able to view my website onlien until it does?
