Other than the fact that much of mathematics is about patterns, NO.
As 20569.8 is not palindromic, any number that is like it must contain that property and similarly be non-palindromic, so no.
There are 90 palindromic numbers between 100 and 1000
There are more 12-digit palindromic numbers than 11-digit palindromic numbers. This is because the number of possible 12-digit palindromic numbers is greater than the number of possible 11-digit palindromic numbers. In general, the number of palindromic numbers of length n is 9 * 10^((n-1)/2), so for 11-digit palindromic numbers, there are 9 * 10^5 = 900,000 possibilities, while for 12-digit palindromic numbers, there are 9 * 10^6 = 9,000,000 possibilities.

There are not just 13 non-palindromic numbers. Most numbers are non-palindromic.

No.
Nobody went out to create them: some numbers simply happen to be palindromic and others don't.

Well, honey, there are 18 palindromic numbers between 10 and 200. Palindromic numbers are like your favorite guilty pleasure - they read the same forwards and backwards. So next time you see a palindromic number, give it a little wink and a nod for being symmetrical in all the right places.
I guess that the smallest would be zero, if you don't consider negative numbers. There is no largest palindromic number - you can make them as large as you like.
