I think it will improve, but not to the 50% figure that was supposed to occur last year. The M3 hardware raytracing might eventually lead to a 20% AAA gaming market share in a couple of years. But hardware isn't the only need. Apple needs to get serious and buy a studio or two.
Buying studios is the right way if Apple wants to make a gaming console. But if Apple wants to compete with PC gaming, it needs to change its business practices.
First of all, Apple needs to tell developers well in advance what to expect from future hardware. Game development takes years, and people want to see games that take advantage of new hardware features before that hardware is replaced by even newer hardware.
Then displays. Games benefit from large displays with high refresh rates, while Apple prioritizes small displays with high resolution and high quality. Macs don't work well with some external displays, and macOS doesn't look as good as other operating systems without a retina or near-retina resolution.
And hardware configurations. Apple treats RAM and SSD as expensive upgrades with low baselines. Storage space is particularly problematic, because games tend to be big. If you buy a gaming PC today, 16 GB / 1 TB is the low-end option, comparable to consoles released a few years ago. Midrange is 32 GB / 2 TB and high end is 64 GB / 4 TB. The same holds for Macs used for gaming, regardless of which configurations Apple sells for other purposes.
Weak GPUs used to be an issue back in the Intel days, but not so much anymore. You are not going to get a high-end gaming experience on a Mac, but the GPUs are now fast enough for most people.
