Since the church only recognizes sacramental marriages, what are we suppose to think of people who are not catholic that get married civilly? (one man and one woman of course).
You do not have to be Catholic to marry sacramentally.
Catholic rules on marriage apply only to Catholics. Non-Catholics marry validly when it is recognized in their own religious community,. If a Protestant church recognizes marriage by a judge then the Catholic Church also recognizes it. (This assumes that the couple is free to marry, not closely related, etc.)
If the marriage takes place between two people who are baptized, then the marriage is not only valid but sacramental.
What we are supposed to think about non-Catholics who marry civilly is that they are married.
Your supposition is a little off. The Church recognized sacramental marriages and also natural marriages. As has been pointed out, non-Catholic Christians who marry civilly have Sacramental marriages. If one or both of the spouses are non-baptized, it’s a natural marriage but fully recognized by the Church.
The Catholic Church recognizees both natural and sacramental marriages. Natural marriages involve one or two unbaptized people. Sacramental marriages involve two baptized people, Catholic or not.
Non-Catholic civil marriages are valid marriages. If both people are baptized, they are valid and sacramental. If one or both are unbaptized, it is a valid, natural marriage.
The problem here is that you think a sacramental marriage is determined by who the officiant is and where it takes place, rather than by what really determines it, the baptismal status of the two people getting married.
