Jungler might choose not to gank your lane even if you're losing hard and getting pushed/dived.

As a jungler, I can tell you that gank decisions are based on the potential of allies/threat of ennemies. I mean, the jungler tries to deny ennemies who snowball if fed, and feed allies who snowball if fed. If you're 0/5 top, getting dived etc. by Karma but the jungler gets your Zed mid 10/0 and to the point where ha can 1v5 the ennemy team, you're gonna win the game anyway.

That being said, if you're feeding a snowball champ (lets say Akali) and other lanes are OK but cant snowball that hard, the jungler might want to help/camp you. It's all about judging which lane needs help, which is not necessarily the lane who is getting raped.
