What am I talking "kaka" about?
As a senior pentester yes you need all the above but by the time you are considered senior you have 5 years experience and many certs.
I can see from what you have written you know nothing about security or working in a security team.
5 years of IT experience is nothing.You still a noob.There is no ways you will be an expert in all those fields.In fact you can have 20 years IT experience and wont be an expert in all those various fields.
