There's a basic question for you all. I noticed that while taking off,
with calm winds, the airplane always tend to go on left side off the
runway.

One of the causes of left turning tendencies in single engine planes
is torque. The slower the speed and the greater the power the more
pronounced the effect. At take off you have very high power and very
low speed so you get a lot of left turn. This is also a problem in
power on stalls.

The rotating prop wash curls back round the fuselage of the aircraft and
strikes the tail plane. This pushes the tail to the right, which makes the aircraft
turn to the left. Thats why you keep right rudder pressure on during take off.
