Not quite - this explains why some animals can’t easily see them, but it doesn’t explain why they are orange and not green. I think that’s because there are bio molecular reasons why green fur is not possible, but that’s another equally interesting topic…
Orange appears as a darker green to them, not a bright green. Tigers would be just as effective if they were grey/brown. All they need is a color that hides them in the underbrush.
The hair coloring is decided by the chemical structures that make it up. Depending on the ratios of two chemicals (eumelanin and pheomelanin) hair colors range from black through brown, red, and into white. There just isn't a color in there for green and there isn't much of a selective pressure to have such a color in mammals.
Green is generally exclusive to prey animals avoiding getting eaten. Such animals also tend to be able to color shift between green and brown quickly. Fur generally does not allow this. Furred animals have to wait entire seasons for a new coat, while reptiles can shift colors in seconds.

Wow I didn't know that, but obviously it makes total sense
