Wireshark/tcpdump every network/security person should know how to use.
If you are going into pentesting then you need to know nmap/backtrack/metaspolit and a bunch of other tools. Its not just limited to one tool.

Its not really which tool is lucrative but rather what field is lucrative. They all have their own tools.

After N+ start with CCNA Security

You could end up using all the tools you mentioned plus many many more. Those tools will not make you a security expert or anything like that, it's just some of the software you would end up using if you are in that field

A tool is not lucrative. Rather understand first how a packet is formed and looks like.

Agree on this.
These would all be useless unless you understand what you are looking at and trying to achieve.
For example if you learnt how to use basic functionality of wireshark you can filter, capture packets, do some correlation, but so what? Do you understand how connections work? What you are looking at, why the MSS size changes, why the window size changes, what a RST is and why it would occur etc.

Tools simply help perform a function in an easier manner or provide information for you to analyze. Without knowing what function or output you would like to achieve or understanding what you are analyzing, there is zero benefit to learning the tools

CCNA is probably your best best if you are looking at getting into networks/security. Seen lots of security guys not actually know the basics of networking which makes it like a hit and miss most of the time.

Get your basic networking right and the rest isn't actually that difficult.
