I’ve just started developing games with UE5 and in a video I watched, he makes a simple walking animation and when I do the same, my characters seem to lag, what is the error here?

Seems like your animation is not in place. When you download it from Mixamo, make sure to tick the In Place checkbox 
What I see is the animation does not match the rate scale of the movement component. You could try increasing the speed by opening the walk cycle take and in the animation setting change the “Rate Scale” to match the MC speed by increasing the scale to say 1.5 to start and then adjust to taste
