The lyrics of "30 For 30" present a rich tapestry of emotions and experiences that resonate deeply with listeners. The title itself, "30 For 30," suggests a sense of readiness and resilience, as if SZA is prepared to face whatever challenges come her way. This phrase can be interpreted as a metaphor for being fully committed and invested in her relationships, akin to a sports player giving their all in a game.

In the opening verses, SZA sets the tone by expressing her desire for genuine affection. She contrasts superficial relationships with the deeper connections she craves, highlighting her self-worth and the importance of loyalty. This theme of self-empowerment is prevalent throughout the song, as SZA asserts her needs and boundaries in love. The lyrics convey a sense of vulnerability, as she navigates the complexities of her emotions while maintaining a strong sense of self.

Kendrick Lamar's verse complements SZA's narrative, adding another layer of depth to the song. His reflections on love and loyalty echo SZA's sentiments, creating a dialogue that emphasizes the importance of mutual respect in relationships. Together, they explore the emotional turmoil that often accompanies love, showcasing both the highs and lows of romantic connections.

The repeated phrase "I'm thirty for thirty" serves as a powerful mantra, reinforcing SZA's determination to confront her challenges head-on. It encapsulates her readiness to engage with her feelings and the complexities of love, while also asserting her worthiness of genuine affection. This duality of confidence and vulnerability is a hallmark of SZA's artistry, making her relatable to many listeners who have experienced similar struggles in their own relationships.

Musically, the song's production, which samples Switch's "I Call Your Name" and Rich Boy's "Throw Some D's," adds a contemporary flair that enhances its emotional impact. The trap influences create a dynamic backdrop for SZA and Lamar's introspective lyrics, allowing the song to resonate with a modern audience while still paying homage to its musical roots.
