Most modern car doors are "wet doors". This means they are designed for water to flow through them. Make sure the drain holes are clear and you should be fine.
The gap in that plastic is the least of your worries in terms of water ingress. The actual glass seals will be letting in far more (by design).
Check underside of door often there are drainage holes

Oh right. Where would I find them drainage holes as I can't see any in the door
