Welcome to the lowend daytripper.
(And welcome to TalkBass.)
Beginning bass guitar is different for everybody and you can approach it in different ways.
I assume you have no musical experience whatsoever at this point. (You didn't mention any previous instrument in your post.)
There is no problem with using tablature.
Before bass I played clarinet and could read sheet music. But I never could sight read very well, I had a good memory for melody and big musical pieces that helped me.
When beginning bass I used tablature, nothing wrong with that.
Don't make it to hard, make it comfortable for you to learn.
But reading tablature counts for nothing if you don't know any basic music theory.
Start with learning scales, different keys and modes.
Then progress to time signatures and paces, rythm and groove is important for a bassist.
Then study how chords (arpeggios) are build and how you can apply them.
Take it easy on technique, start with plain fingerstyle (or even pick if you think that's your thing) and learn stuff like slapping, tapping, fingerpicking, etcetera... and where to pluck the strings afterwards.
Although learning to eliminate fretbuzz is the first thing you should tackle.
And practice your fingers: force and flexibility.
First focus on getting the notes right and finetune your sense of rythm.
You can pick up a metronome for cheap, I advice this.
Learn where every note is on your fretboard. Do not memorize this mindlessly but try to understand how the structure.
All this music theory should not get in the way of the fun. But I advice to spend some time on it.
For example: an hour of studying and practicing theory followed by an hour of practicing songs you'd like to learn.
You can also find some good practice books for bass guitar.
From complete beginner to certain genres to certain techniques.
See what aplies to you and what genre you want to play. (Or be good at any genre if you're going for that.)
As a beginner try to hang out a lot in the General Instruction and Technique forum here on TalkBass.
And stay away from the Basses, Effects and Amps forum.

GAS (Gear Aquisition Syndrome) will get in the way of progress to often.
Again, welcome, and enjoy your new hobby.
Succes.
