In the UK your dishwasher is typically connected only to the cold water intake, so that’s not a problem unless you have multiple showers in your house… that said, water heaters are often limited to either heating or hot water (not both at the same time), but that’s not an issue in practice since you’re not going to be using the hot water for long periods of time.

They do, they’re just not connected to the dishwasher so don’t need to be factored into its energy usage.

But then shouldn’t there be a delay when using actual Chrome?

How would you even hit a 3.3 TB limit a month in normal usage? AAA games these days are hitting 100 GB but how many of those are you going to download in a month? Streaming Netflix 24/7 will also not get you there, unless maybe it was 4k content the whole time. Maybe if you’re pirating uncompressed Blu-ray rips?
