There is a statement that I can't give a reference;
"Since the timing characteristics of symmetric algorithms are not as key dependent as asymmetric algorithms, they are more resistant against timing attacks."
Is it true?

This is largely but not absolutely true.
Data-dependent (including key-dependent) timing characteristics come essentially from
Note: the quote suggests that only key-dependent timing variations matter. This is not entirely true: any timing dependency on non-public data could in theory be a potential attack vector, in that it can leak information on the data.
