It means that there is no guaranteed win, because there is so many possible moves there is never a guaranteed win from the start of the game. However, there is something called a tablebase which I think is able to solve chess and guarantee a win when there are 7 or less pieces left on the board.

Any chess position with 7 pieces or less is solved. That is in every such position you can tell which moves lose, win or draw. Those solutions are called tablebases. Positions with more than 7 pieces are generally not solved (although there can be some that are). Once tablebases are extended to 32 pieces, chess will be completely solved. But that is not going to happen anytime soon.

Yeah the memory for just the 7 moves is something like 100 terabytes it's going to be centuries yet until chess is solved. Unless we get some huge advancement in quantum computing.
What does it mean by chess is not solved? Didn’t we solve it when we checkmate?
