Well it depends, what do you want?
It is evident that if you enter 4 years you will not be with people of your same generation (mostly), is it a problem? I don't know, it depends on you, because I remember the case of a person who had entered years later, he was more adult than the others, he was not separated or anything, but he himself said that he saw them as children, because he had already been through things of that age
In labor terms, they may question it, considering the current absurd competition, if he is able to graduate within the corresponding years and make enough contacts, there would be no problem.
Looking at it from one point of view, it's good, you've lived longer, you'll have more clarity on what career to choose, apart from being more mature than when you were 18
but if you are worried you could first study a technician, work and then go for engineering
greetings, be well
