Pretty much, many situations are avoid with just a bit of forethought and a few basic rules, people will often for example wander in a random manner which makes it very difficult for a search party to find them, especially when they leave no markers.
Back to equipment, one thing that should be mentioned is that the actual enhancement that better gear makes is usually fairly small. With even a moderate amount of experience, the differences among blades is usually small, as in a percentage, not many times to one.
I usually recommend lower end blades to start for a few reasons, first off all it gives you a cheap place to experiment and learn what you can and can't do. One the blade eventually gives out (during practice) you can then figure out what you need/want for the real thing.
Even when you get your ideal blade, keep using other ones, even the ones that are less than optimal as you can never tell when you may be forced to rely on it. It isn't like you can always simply say "No, I don't want that machete, please give me a nice double bitted felling axe, medium density grind."
You may have to cut wood with a normal machete some day, so it is a good idea to figure out how to do so, you can't use the same technique you would with a bolo or golok, as you are likely to either break the machete, cause yourself excess discomfort and fatigure which will increase your chances of injury and breaking the machete.
As a basic starting kit I would recommend :
Martindale Golok

This will handle a very wide range of tasks. Once you want to move up to handling heavier wood, I would get a good saw, I like this one :

I would recommend strongly though, before you attempt to fell serious wood, do so reading on felling and if all possible talk with someone who has done it, it is very easy to kill yourself cutting down large wood, and usually there is no need to do so anyway. If you start with an axe this is critical, ask specifically about felling leaners and how to deal with widowmakers

Once you have a basic skill set you upgrade the equipment using your experience to guide you on what is better, what did you find lacking in regards for the ability of the tools to match your abilites and the needs demanded by the enviroment - ask around and find out what can address these issues.

[*] the answer is easy, you don't cut them down, the problem is mainly realizing this and to identify them.
