EA has parted ways with world football governing body FIFA after a 30-year partnership, and is now going it alone, rebranding its soccer series as EA Sports FC. The end of EA's agreement with FIFA likely means that it has lost the right to sell even earlier games under the FIFA name.
Long story short: yes, FIFA 23 will be the last FIFA-branded game that EA Sports makes for the foreseeable future. However, EA Sports will continue making football games, with their next one due to be called EA Sports FC - and it sounds like this rebranded effort will contain a lot of familiar elements for fans.
