It depends what you mean by double stranded.
If you mean two separate RNA strands, perfectly complementary to one another and existing as a basepaired structure in the cytoplasm, then no. Double stranded RNA like that only occurs in some types of viruses (and cells infected by them... so I guess the cytoplasm of a cell infected by a double stranded virus might have a lot of this kind of double stranded RNA).
However, if you mean double stranded in the sense of a single RNA molecule folding back on itself and basepairing with itself - forming stem loops and more complicated structures - that kind of RNA double-strandedness is extremely common. All tRNA's and rRNA's for example exhibit this kind of double-strandedness. Nucleic acids are unstable in single stranded states and will spontaneously fold back on themselves if there is no other strand to basepair with.
Nucleic acids are inherently unstable in a single stranded state. Thus,
Erwin Chargaff discovered that the amount of adenine in DNA always equaled the amount of thymine. This observation is part of his rules, which state that in double-stranded DNA, the amount of guanine equals that of cytosine as well, highlighting the base pairing relationships crucial for the structure of DNA.
In DNA, guanine (G) pairs with cytosine (C) through hydrogen bonds, which means that in a double-stranded DNA molecule, the number of guanine bases is generally equal to the number of cytosine bases. This relationship is part of Chargaff's rules, which state that the amount of adenine (A) equals thymine (T) and the amount of guanine equals cytosine. However, in RNA, which is single-stranded, there is no strict pairing, so the number of guanine and cytosine bases may not be equal.

The nearly 1:1 ratio of adenine (A) to thymine (T) in DNA is explained by Chargaff's rules, which state that in double-stranded DNA, the amount of adenine will always equal the amount of thymine due to base pairing. Each adenine nucleotide forms hydrogen bonds with a thymine nucleotide, ensuring that they are present in equal quantities. This complementary pairing is essential for the stability and fidelity of the DNA double helix structure.
In a strict sense no. mRNA always consists of a single RNA strand. In another sense, yes. Nuclei acids are inherently unstable in a single stranded state - the nitrogenous bases will spontaneously basepair with any nucleotides they encounter. As a result, most RNAs will spontaneously fold back on themselves, the single RNA strand basepairing with other regions of itself. That said, because the sequence will never be perfectly complementary, it's unlikely that much of the mRNA will be double stranded, but it will probably have a few segments with a double stranded character.

There are three main differences between RNA and DNA: The sugar in RNA is ribose instead of deoxyribose, RNA is generally single-stranded, and RNA contains uracil in place of thymine.
