yes A scalar is simply a directionless numerical quantity (ie: 44 meters, 2525 amperes).
A vector is a quantity which has both a numerical value (magnitude) and a direction (ie: 44 meters eastward, 2525 amperes to the right).
The initial speed of an object simply refers to how fast it is moving when it begins its motion (it doesn’t take into account whether it is travelling north, south, left, right, etc.). It is a scalar.
The initial velocity of an object, on the other hand, has both a magnitude (speed) and a direction (ie: 10ms10ms to the left). It is a vector.
So, while an object’s velocity would change with a change in direction or magnitude, the speed would only change with magnitude.
