My teacher confuses me by saying x is a random variable and sometimes by saying x is a random vector.

The terms can be used interchangeably but one has to be careful since a multivariable random variable is a random vector
For example:
1.A random variable is a function say X=(X1)
2.However a multivariate random variable is random vector X = (X1, ..., Xn).
I hope that answers your question.

A random variable is generally a scalar, while a random vector is a vector. Examples: x is a random variable uniformly distributed between 0 and 100. X is a random vector with the i-component ranging from -5 to +10, and the j-component ranging from 0 to +3.
