If you do that any packets that don't match acl 101 or acl 102 and there is no explicit route in the routing table they will be routed to null0. So it depends on whether you want that or not.
I explained this before in that if a packet does not match any PBR route map statements then those packets will be routed using the routing table. However in your example in the last statement, because you have not specified a match statement, all packets that didn't match the acls or have an explicit route in the routing table will be routed to null0.
It depends what you want. If you want any packets that do not match either acl 101 or acl 102 to be routed using the routing table then no you don't need it. If there is no match for a packet in the route map then the router simply looks into the routing table to see where to forward the packet.
If there is a default route in the routing table and no more specific route it will use that.
