If anyone will take a Concordance and read carefully the various passages in which the term “world” (as a translation of “kosmos”) occurs, he will quickly perceive that to ascertain the precise meaning of, the word “world” in any given passage is not nearly so easy as is popularly supposed. The word “kosmos,” and its English equivalent “world,” is not used with a uniform significance in the New Testament. Very far from it. It is used in quite a number of different ways. Below we will refer to a few passages where this term occurs, suggesting a tentative definition in each case:
“Kosmos” is used of the Universe as a whole: Acts 17: 24 – “God that made the world and all things therein seeing that He is Lord of heaven and earth.” is used of the Universe as a whole: Acts 17: 24 – “God that made the world and all things therein seeing that He is Lord of heaven and earth.”
“Kosmos” is used of the earth: John 13:1; Eph. 1:4, etc., etc.- “When Jesus knew that his hour was come that He should depart out of this world unto the Father, having loved His own which were in the world He loved them unto the end.” “Depart out of this world” signifies, leave this earth. “According as He hath chosen us in Him before the foundation of the world.” This expression signifies, before the earth was founded—compare Job 38:4 etc.
“Kosmos” is used of the world-system: John 12:31 etc. “Now is the judgment of this world: now shall the Prince of this world be cast out”— compare Matt. 4:8 and I John 5:19, R. V.
“Kosmos” is used of the whole human race: Rom. 3: 19, etc.—”Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.”
“Kosmos” is used of humanity minus believers: John 15:18; Rom. 3:6 “If the world hate you, ye know that it hated Me before it hated you.” Believers do not “hate” Christ, so that “the world” here must signify the world of unbelievers in contrast from believers who love Christ. “God forbid: for then how shall God judge the world.” Here is another passage where “the world” cannot mean “you, me, and everybody,” for believers will not be “judged” by God, see John 5:24. So that here, too, it must be the world of unbelievers which is in view. is used of humanity minus believers: John 15:18; Rom. 3:6 “If the world hate you, ye know that it hated Me before it hated you.” Believers do not “hate” Christ, so that “the world” here must signify the world of unbelievers in contrast from believers who love Christ. “God forbid: for then how shall God judge the world.” Here is another passage where “the world” cannot mean “you, me, and everybody,” for believers will not be “judged” by God, see John 5:24.

“Kosmos” is used of Gentiles in contrast from Jews: Rom. 11:12 etc. “Now if the fall of them (Israel) be the riches of the world, and the diminishing of them (Israel) the riches of the Gentiles; how much more their (Israel’s) fulness.” Note how the first clause in italics is defined by the latter clause placed in italics. Here, again, “the world” cannot signify all humanity for it excludes Israel!
“Kosmos” is used of believers only: John 1:29; 3:16, 17; 6:33; 12;47; I Cor. 4:9; 2 Cor. 5:19. We leave our readers to turn to these passages, asking them to note, carefully, exactly what is said and predicated of “the world” in each place. is used of believers only: John 1:29; 3:16, 17; 6:33; 12;47; I Cor. 4:9; 2 Cor. 5:19.

Thus it will be seen that “kosmos” has at least seven clearly defined different meanings in the New Testament.
"Kosmos" in John 3:16 - by AW Pink
Just like the word all does not mean all, all the time, the word world does not mean every single person all the time.
Christ is said to have laid down His life for all and also laid down His life for many which logic demands must mean that it is the all of the many and not every single person in the world.
