That calculator isn't telling you the risk of hospitalisation per case, but the risk of hospitalisation over a 90 day period during the first peak of the pandemic.
The two are very different. The calculated risk includes the fact that not everyone (or even most people) will get covid during that 90 day window. It's also based on the statistics for the original covid variant - by all accounts Delta is both more transmissible and more likely to cause hospitalisation.
For example, a 25 year old man with no co-morbidity who receives a positive covid test has a 1.6% chance of hospitalisation. Obviously not everyone with covid will receive a positive test (I've seen an estimate of 1 in 4 are tested) - so perhaps that rate is actually 0.4%. That's way, way higher than the 0.002% you said.
Ultimately if covid is endemic, you will get it. At that point, even as a 25 year old, you're risking hospitalisation.
That calculator includes an estimate of likelihood of catching covid - so the actual risk of hospitalisation for someone who does catch covid is way, way higher - for a 25 year old man in the US it's about 1.6%.
Ok, 0.008% if you want. Sure feels like an argument for argument sake. I can find a list of odds of things that will hurt/kill a 20-something where the percentage is greater than 0.008 if you'd like.

The likelihood on a per-case basis is significantly higher. The Economist has a tool here: https://www.economist.com/graphic-detail/covid-pandemic-mort...
