In Jewish tradition (which is the milieu in which Paul was educated), there is a mention together of three heavens, as well as seven heavens.
Targum of 2 Chronicles 6:18
שמיא עילאי ושמיא מיצעאי ושמיא תתאי
"the supreme heaven, and the middle heaven, and the lower heaven"
According to the Babylonian Talmud, tractate Chaggiga 12b, Resh Lakish said there are seven heavens.
ר"ל אמר שבעה ואלו הן וילון רקיע שחקים זבול מעון מכון ערבות

In the Psalms, we read that the heavens declare the glory of God. In this case, the psalmist seems to be referring to what we call "space", as he asserts that in the heavens is where the sun resides.
The heavens declare the glory of God, and the sky above proclaims his handiwork... 5 In them he has set a tent for the sun, which comes out like a bridegroom leaving his chamber, and, like a strong man, runs its course with joy. 6 Its rising is from the end of the heavens, and its circuit to the end of them, and there is nothing hidden from its heat.

From the FaithLife Study Bible, this (three heavens) represents the understanding of the universe held by the Greeks:
According to ancient cosmology, there are seven levels: the sky, the clouds, the sky above the clouds, the firmament, the waters above the firmament, the heavens, and the heaven of heavens, where God dwells. The three heavens view understands the first heaven to be the visible sky or the “firmament” (see Gen 1:8 and note), the second heaven to either be the “heavens” or the division between the “heavens” (the “waters above the firmament”; Psa 148:4), and the third to be the “heavens of heavens” or “highest heavens” (1 Kgs 8:27; Psa 148:4). All views agree on the places, but they label them differently.
In a nutshell then:
In identifying "the third heaven," Paul is saying he was in the presence of God directly.
