Advise me on whether I should buy Apple Macbook

Both @Phil0124 & @Servant of Cats are 100% correct.

I would just like to add that Macs have never been considered gaming computers. Yes, there may be a few games that may work fine on a Mac, but you need to do a lot of research these days to make sure the games you wish to play are actually compatible with the M-series Macs and macOS Sequoia. Don't buy a Mac with the sole goal of playing games as you will be disappointed.

Very few games are designed by the original game developer to work on a Mac. Usually a Windows game will be ported to the Mac by a third party developer such as Feral Interactive which can introduce some issues for an online component of the game where it is not always possible to play online with Windows gamers. Since most games are designed for Windows...most are never ported to other systems (other than game consoles), so these days in order to play a Windows game on a Mac requires the use of third party software such as CrossOver Mac which can allow some Windows software & games to run on the Mac (even an M-series Mac), but this is not perfect since a game update could break whatever compatibility existed until the third party app can be updated to fix the issue (possibly). This option is not always perfect or reliable when it comes to M-series Macs and is always a work in progress. Plus any online games utilizing an anti-cheat component is unlikely to work on a Mac when using Crossover Mac or similar software.

Plus you need to make sure your Mac meets or rather exceeds the Recommend System Requirements for each game you wish to play. This is extremely difficult to figure out with Macs especially these days since most games were developed for Intel Macs and may not always be compatible with an M-series Mac even with Rosetta. Plus the macOS requirements can be difficult to fathom as well since a game that says "compatible with macOS 10.13+" may not really be compatible with macOS 10.15+ if they are 32bit apps. Game developers tend to rarely provide game updates after a year or two and with macOS changing sometimes very drastically every year, this can lead to issues. Make sure to check the games' forums for recent reviews & discussions regarding current M-series Macs and Sequoia to see if anyone is having issues with a particular game.

Do your research.

If gaming is your focus, then purchase a Windows computer that meets or rather exceeds the Recommended System Requirements for all the games you want to play. Or purchase a game console such as XBox or PlayStation.

Plain M-series chips – like the one in that Mac – have entry-level GPUs. Within a given generation of Apple Silicon chips, you get a stronger GPU (more cores) as you go from a plain chip, to a Pro chip, to a Max chip. M1- and M2-series chips lack the hardware ray-tracing support introduced with the M3.

So if I was picking a Mac laptop for running something like X Plane, it would probably be a 14" or 16" MBP that had a M4 Pro or M4 Max chip. Something with more RAM, more CPU cores, and more GPU cores than a discontinued 13" M2 MacBook Pro.

I would go further and suggest that if the main thing you will be doing is gaming, you may be best off with a high-end Windows/Intel machine – due to applications availability. No one computer is best at everything, so there's a rule of thumb that you should pick the applications that you want to run, and then go looking for computers which would do a good job of running those particular applications.

In this day and age 8GB of RAM is simply not enough for anything.

And the price is close to a brand new M4 with 16GB of RAM and 1TB of Storage, so no, its not a really good purchase at this point.
