Is there any difference between the following 2 sentences or they are same?
I found out its secrets.
I found its secrets out.
There is no difference. Here we are talking about a separable phrasal verb. If the object is a noun, you can put it after the particle or before it. If the object is a pronoun, it must be put before the particle:
I found out a secret. = I found the secret out.
She found out the truth. = She found the truth out.
BUT
I/she found it out.
