You're comparing completely different statistics. The 3% is the infection hospitalization rate; in other words, the odds of being hospitalized once infected. The rates from your source are the total number of people per 100k who are hospitalized for covid in a given week; it does not mean they only have a .05% chance of being hospitalized once infected, it means .05% of the entire age cohort are hospitalized from covid that week.

edit2: actually, I see the denominator there is total population not cases but I still don't follow.

There have been 19,850,744 cases in 18-49 year olds [0] and 63,207 hospitalizations [1] which suggests at 0.3% infection hospitalization rate..
