The acidity of the vinegar/ pickling solution is high enough to burst the bacterial cell walls, this killing them. This also explains why vinegar makes a very good cleaning solution.

prior to the canning all bacteria in the food are killed and the canning prevents new bacteria from infecting and spoiling the canned food Food that is put into canning jars is not sterile, thereby allowing bacteria to grow.

Why fermented foods have longer shelf life?

The vinegar in pickled foods raises the pH level and inhibits growth of bacteria. This is why pickled foods last longer. Pickled foods that processed in a hot water bath last much longer because the hot water bath sterilizes the jar and the contents and draws air out of the jar. This makes it almost impossible for the food to develop bacteria and spoil.

You don't pick them yourself... you ask Peter Piper to pick them for you as in the old rhyme Peter Piper picked a pickled pepper If Peter Piper picked a pickled pepper Where's the pickled pepper Peter Piper picked!! Bit of a tongue twister! You can not "pick" a pickled pepper, it has already been picked from the plant and pickled in a jar. You could grab or "pick" it out of a jar of pickled peppers, but you can not pick a pickled pepper fresh from the pepper plant like one might be mislead to think from the tongue twisting rhyme.
