I am looking to buy an external monitor and came across the samsung odyssey G9 superultrawide monitor. will my macbook pro M2 chip 2022 be able to support 5120x1440p at 120hz over a thunderbolt cable?
A MacBook Pro with a M2 chip, from 2022, would be a 13" model with a plain M2 chip, two USB-C / Thunderbolt 3 ports, and no HDMI port. 14" and 16" models with M2 {Pro/Max} chips and HDMI ports didn't come out until 2023.
There appear to be several Samsung Odyssey G9 monitors.
G91SD, G95SC, and G95SD all appear to be 49" dual QHD monitors with DisplayPort 1.4, HDMI 2.1, and Micro HDMI 2.1 interfaces. No evidence of Thunderbolt inputs or even USB-C (DisplayPort Alt Mode) inputs, although there are USB-C ports for USB data only. The first one has a 144 Hz refresh rate; the latter two have 240 Hz refresh rates.

Not in this case. The combination of "M2" and "2022" implies that the OP's machine is a 13" MacBook Pro that has a plain M2 chip.
That computer supports a maximum of one external display.
If the monitor supports Picture-by-Picture, the OP possibly could run two cables to the display with the aid of some second-class workaround like DisplayLink, but I don't believe that such workarounds are known for the ability to drive displays at very high refresh rates.

The way that works is to logically divide the display into a left half and a right half. Each is then a relatively easy to support 2560 by 1440 logical display.
Then you use whatever cables and adapters you like, and inside the display, the picture is re-assembled using Picture-By-Picture (cousin of Picture-In-Picture). That display supports those features.
The Mac sees it as an extended desktop, with the two displays concatenated along the correct edge.
Users report that once set up, the feature works as if it were ONE display, no compromises.

You are quite right, I stand corrected.
Not likely, unless you have a model Samsung display with a DIRECT ThunderBolt input, and are using an ordinary Thunderbolt cable that is no longer than 0.5 meters long. (longer ACTIVE ThunderBolt cables are available, but start at US$125)
-OR- only on 2023 or later model MacBook Pro with DIRECT HDMI output port.
Over its DIRECT HDMI 2.1 port, and much longer cable lengths (said to be up to ten feet or so) but you must use certified ULTRA cables.
Adequate adapters to HDMI 2.1 are a hallucination.
Typical specs on that class of Samsung displays suggest they feature 5120 by 1440 at up to 240 Hz.
Video connectivity includes:
HDMI 2.1
HDMI 2.1. micro
Displayport 1.4**
**DisplayPort 1.4 speed using DisplayPort direct or over Thunderbolt os limited to 32.4 G bits/sec HBR3 speed.
That 32.4 G bits/sec DisplayPort 1.4 speed supports a 5K display at 8 bits/color at 69 Hz, or a 5K display at 10 bits/color at 56 Hz.
**DisplayPort data rates over USB-C or with a standalone adapter or adapter/cable (about 14.4 G bits/sec) top out at 4K at 81 Hz for 8 bits/color of 4K at 65 Hz for 10 bits/color.
