I would suggest that as a beginner you don't need anything working against you. now you have been told the clubs don't fit you it will be on your mind.

4 deg is quite a lot, if you hold the leading edges of two 7 irons together with 1 deg lie difference, they will be approximately the width of the grip apart at the top, you can imagine the difference with 4 deg.

If the flex and length are OK you could get them bent to the correct lie for a reasonable price.
