i am not confused about min, max, i understand that these are the lower
limit and upper limit of range min-max.

That's ok.

ok one paramater is the max value!

at this point i see in wiki this

If only one parameter is specified, returns a pseudo-random in the
interval [ 0 , Min [.


it confuses me that

[ 0 , Min [.


i understand it better as 

range
[0 - Max] or in your example range [0, Val2] not Val1.

Because the lower limit is Min=0 and upper limit is Max=Val2.

Example
' Between 0 and 2
PRINT Rnd(2)

Min=0, Max=2
Val1=0, Val2=2

it is equal

PRINT Rnd(0, 2)
Min=0, Max=2
Val1=0, Val2=2
