The Wikipedia article lists the first happy numbers as 1, 7, 10, 13, 19, 23, 28, 31, 32, 44, 49, ..., so the answer is clearly no.
The number seven or eleven are considered lucky when it comes to luck number 13 is suppose to be a bad luck number.

Well, isn't that just a happy little number we have here? The value of 3 in 13 is simply 3. It's a small but important part of the number, adding its own unique touch to the overall value of 13. Just like every element in a painting, every number has its place and purpose.
A number is divisible by 13 if it is a multiple of 13. In other words, 13 times a number results in a big number that is divisible by 13.

Ah, what a happy little question! The nearest whole number to 13.1 is 13. You see, when a number is right in the middle, we can round it up or down depending on what's closest. In this case, 13 is just a little bit closer to 13.1 than 14. Just a happy little rounding decision to make!
Add the squares of the digits of a whole number to make a new one. If you repeat this process and end up with the number 1, you have found a happy number. For example: 32= 9+4=13, 1+9=10, 1+0=1. Therefore 32 is a happy number
22 x 13 = 52
A happy prime is a number that is both happy and prime.A happy number is defined by the following process. Starting with any positive integer, replace the number by the sum of the squares of its digits, and repeat the process until the number equals 1 (where it will stay).Happy numbers below 50 are 1, 7, 10, 13, 19, 23, 28, 31, 32, 44, and 49. The five numbers in bold are also happy primes. There are a number of techniques for finding happy primes but for prime numbers of a few digits then the squaring and summing process is just as efficient.
