They voted in 2020 for statehood.

"Should Puerto Rico be admitted immediately into the Union as a State?"
Yes: 655,505 (52.52%)
No: 592,671 (47.48%)

True, but didn't that vote have a pretty low turnout, as most of the anti-Statehood folks decided to boycott the vote for some reason?

No, its turnout was 54%. They had previous referendums boycotted and receiving like 23% turnout, but over 50% turnout is legitimate under any country’s laws.
