NO, as stated in OP
In order to obtain the highest degree of the celestial kingdom, we must enter into the new and everlasting covenant of marriage
Kingdoms of glory (3 kingdoms)
From another revelation to the Prophet Joseph, we learn that there are three degrees within the celestial kingdom. To be exalted in the highest degree and continue eternally in family relationships, we must enter into “the new and everlasting covenant of marriage” and be true to that covenant. In other words, temple marriage is a requirement for obtaining the highest degree of celestial glory.
On degrees in terrestrial/telestial kingdom:
Elder James E Talmage
The three kingdoms of widely differing glories are severally organized on a plan of gradation. The Telestial kingdom comprises subdivisions; this also is the case, we are told, with the Celestial; and, by analogy, we conclude that a similar condition prevails in the Terrestrial. Thus the innumerable degrees of merit amongst mankind are provided for in an infinity of graded glories
Elder Bruce R McConkie
Rewards granted individuals in eternity will vary between and within kingdoms. Only those who are sealed in the new and everlasting covenant of marriage and who thereafter keep the terms and conditions of that covenant will attain the highest of three heavens within the celestial kingdom. (D. & C. 131:1-4.) Inhabitants of the telestial kingdom will differ in glory among themselves "as one star differs from another star in glory." (D. & C. 76:98; 1 Cor. 15:41.) Similar variations will exist among inheritors of the terrestrial kingdom. (D. & C. 76:71-79.)

But actually yes
All who are worthy to enter into the new and everlasting covenant of marriage will have that opportunity, whether in this life or the next.
Fundamentally, what decides the future fate is the own decisions and wishes, not outside factors that may, in this life, have prevented marriage.
