Yes, that's right, always or at any time. The phrase "all I ever need" typically expresses a sense of completeness or satisfaction. When someone says "you're all I ever need," for example, they're conveying that the person they're speaking to fulfills all their emotional, physical, or material needs. It implies that nothing else is necessary or desired because that person or thing satisfies them completely. It's often used in romantic contexts to convey deep affection and attachment.
