"Silly boy, it's all about trust."

What's the difference between trust and faith?

I'm not distinguishing. I regard "trust" as the real meaning of "faith".
John's gospel talks of believing "that" (i.e. accepting that a statement is true) and also of believing "in" (i.e trusting a person). My case is that believing "in" is what really matters, even though the church has historically focussed on believing "that" because it is easier to teach and monitor.

I see faith as a spiritual element and trust more the confidence of something/someone.  As per internet definitions that I've looked up.

There's definitely a difference.

The Biblical God is a "someone". That is the point.

The Biblical God is a concept, not someone who will help you move or drive you to the airport.

 "Someone who will drive you to the airport" is also a concept, behind which there may or may not be a reality (depending on the arrangements that have been made). The two things are not mutually exclusive.
Biblical theology obviously rests on the assumption that there is a reality, in the same way, behind the concept of the God who is acting and communicating. And I am not offering to prove that Biblical theology is right; my task is only clarifying what it says.
