Just like all vaccines, it cannot guarantee that you won't "catch" Covid. It just makes it so that when the Covid virus enters your body (you catch it), your immune system immediately destroys it.
So you could be "sick" for a few seconds or a few hours (technically speaking, though you'd never know it. A single virus has entered your body and started replicating, but your immune system recognizes it right away and kills it before it spreads from the first infected cell to any other cells...)
But in reality what happens is that you will be immune (for all intents and purposes) from becoming anything more than not-at-all symptomatic to mildly symptomatic. Only in very unusual cases would a person who is vaccinated become seriously ill; and in some of the vaccine trials (J&J for example), the vaccine was 100% effective in stopping serious illness - not a single person was hospitalized who got this shot, and zero people ended up dying.
So, you get your shot to prevent yourself from becoming seriously ill. You get the shot so that if you do get "sick" you almost certainly will only be sick for a few minutes to a few hours, and in the worst case scenario, you are sick for a few days with a mild to moderate illness.
