As I stated above, Allen, all domestic broadband connections are 'asymmetric'. (i.e. the upload speed is slower than the download one). That makes absolute sense as, for example, apart from uploading a very small amount of data when I click on the 'Answer Now' button in this thread (or when, say, I'm sending an email), I, and almost very other internet user, very rarely need to upload data.
Most domestic fibre-based internet connections use BT Openreach's cables, where (irrespective of download speeds) the upload speed is usually fixed at 10 Mbps for the majority of 'budget' services or occasionally at 20 Mbps for 'premium' services. However Virgin Media operates its own fibre-optic cable network and chooses to weight the asymmetry in its services in line with the figures I've quoted above.
If your next door neighbour has a broadband connection advertised as offering 20 Mbps through Openreach's cables, and you've got a 54 Mbps service through Virgin's own cables, you'll have a DOWNLOAD speed that's nearly three times as fast as your neighbour gets. However he'll be getting OpenReach's standard UPLOAD speed of 10 Mbps, whereas you'll only be getting 3 Mbps through Virgin's cables, so it will be your neighbour who has the three-times advantage in that respect. So your neighbour will be able to upload files to YouTube at roughly three times the speed that you can, even though he's nominally got a much slower broadband connection.
[BTW: I assume, from your question about YouTube that you managed to work out how to upload a video, so that your wife can view it in hospital].
