I understand the assertion. Wikipedia (amongst other sources) disagrees.

Do you have a citation for this assertion? Because the wikipedia entry on 
Normal_numbers disagrees with you. If you have an equal probability for all 
1-symbol elements to appear in an infinite string (i.e., if every symbol 
appears an infinite number of times) then you have an equal probability of 
every subsequence to show up - i.e., all possible combinations show up an 
infinite number of times.

If you have an infinite number of trials and the letter 'a' never shows up, 
it means it's impossible for the letter 'a' to show up. The probability a 
priori of 'a' showing up is zero, because any non-zero number times infinity 
is infinity.
