1. Till/until refers to a period of time:
I will stay here until Friday

2. By refers to deadlines: meaning not later than
We have to finish our work by three O'clock.

BY means "not later than" so if you say sth like: "You must be at home by 7 o'clock." = it means you must be at home not later than 7 o'clock, you can come at 5 o'clock, 6 o'clock, 7 o'clock but not later that 7.

And sth continues UNTIL (or till) a time in the future:
Fred will be away until Monday. (= so he'll be back on Monday, not sooner).
Compare:
Fred will be back by Monday. (= so he'll be back not later than Monday)

sth continues UNTIL (or till) a time in the future.
sth happens BY a time in the future.

I hope it helps.

I walked till [until] I was tired.
I talked till [until] I was hoarse.
The rain lasted till [until] the morning.
They were at school till [until] 4 o'clock in the afternoon.

"At this time"
Will you be ready to go to school by 9 o'clock in the morning?
He was home by 6 o'clock in the evening.
The meal will be ready by the time you come home.

"Till" and "until" are interchangeable - either can be used.
